Regasm installs shell extension correctly, but heat-generated WXS does not, writes to different registry path - wix

I wrote a shell extension (item in explorer's file context menu), and used WiX's heat to create an MSI from the DLL.
PROBLEM: Installing the MSI does not make the context menu item appear.
In contrast, running Regasm.exe my.dll /codebase makes the item appear.
heat writes registry keys into HKEY_CLASSES_ROOT\, while
Regasm writes registry keys into HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.
I could modify the heat-generated WXS to write to the same registry path as Regasm, but MSDN suggests HKEY_CLASSES_ROOT and apparently some users are not be able to write into HKEY_LOCAL_MACHINE... is there a better solution?

HKCR is an alias for HKLM\SOFTWARE\Classes\ when your MSI package is per-machine. The easiest way to ensure pre-machine package is to set the InstallScope on the Package element:
<Wix>
<Product ...>
<Package InstallScope='perMachine' />

WiX Bootstrapper WPF custom UI

I read and run sample from here.
Some questions:
How I can get actions names during the install/uninstall/remove process?
How I can pass variables and parameters to embedded MSI?
Is any way to get additional information from the embedded MSI (product version, company name etc) as it is done in WixSharp (WpfSetup sample)?
4. How I can get (set) from MSI file INSTALLFOLDER, TARGETDIR and other values?
I'm not sure you can or not. Microsoft.Tools.WindowsInstallerXml.Bootstrapper.BootstrapperApplication will tell you what msi package it is planning or executing, you may also be able to get information about which install action it is executing, check the events that get raised by this during your install process.
2.
In your bootstapper WPF app
//ba is an instance of BootstrapperApplication
this.ba.Engine.StringVariables["ServerInstallLoc"] = "YOUR DATA"
Bundle.wxs
<!-- Install paths provided by the managed bootstrapper interface -->
<Variable Name="ServerInstallLoc" bal:Overridable="yes" Type="string" Value=""></Variable>
And later reference this variable
<MsiPackage Id="MyInstaller" SourceFile="$(var.MyInstallerMsiProjectName.TargetPath)" Compressed="yes" DisplayInternalUI="no">
<!-- Pass wix bundle variable to MSI property -->
<MsiProperty Name="SERVER_INSTALL_OVERRIDE" Value="[ServerInstallLoc]"/>
</MsiPackage>
In your bootstrapper, you can reference properties of the bundled installers. the syntax is: !(bind.packageVersion.PackageName) assuming one of your <MsiPackage> elements is called PackageName. Binder variables reference
For question 4 look at this:
http://www.wrightfully.com/allowing-the-user-to-select-the-install-folder/
You can also look at the Wix managed bootstrapper as I believe it does this as well. You can download the source code here:

How to work with HEAT.exe for dll registry

and i need to register a dll . Right now am registering the dll as below
<CustomAction Id='comReg' Directory='INSTALLLOCATION' Impersonate='no' Execute='deferred'
ExeCommand='"[NETFRAMEWORK40CLIENTINSTALLROOTDIR]regasm.exe" "[INSTALLLOCATION]myProduct.dll" /codebase' Return='check' />
but all are suggesting to use HEAT.exe in internet wherever and whenever i surf . I even have gone through this link. But there they have only the syntax etc. I really dont know how to work with it just by knowing those syntax.
I need some step by step procedure or some good blog which elaborately tell how how to harvest a dll and how to impllement it in to wix code and how the registry will be done , so that i can register my dll based on conditions also.Even i tried this link alse
Regards
Registering a COM component is done through standard Windows Installer actions and tables. Numerous table entries are required so WiX provides heat.exe to harvest COM files. It works by inspecting a file for type libraries and, if the DllRegisterServer entry point is present, running it in a Registry sandbox where changes are intercepted and captured. (In the era of Windows Installer [1999-present], DllRegisterServer is effectively deprecated for any other purpose.)
As you may know, a Feature is the smallest user-selectable unit of installation. A Component is a member of one or Features in one or more Products. Heat creates a component for each file it harvests and a ComponenentGroup for each harvest run. So, you have to pick a ComponentGroup Id and reference it in one or more Features. You also have to pick a Directory Id for the destination of the ComponentGroup.
Now, it is simply a matter of editing your project file to harvest the file. To edit a project file you could use a text editor but Visual Studio is all set up for it. See How to: Edit Project Files.
Add a HarvestFile element to a new or existing ItemGroup, entering the desired ComponentGroup Id and Directory Id
<ItemGroup>
<HarvestFile Include="comserver.dll">
<ComponentGroupName>COM</ComponentGroupName>
<DirectoryRefId>ServerDir</DirectoryRefId>
</HarvestFile>
</ItemGroup>
In your Product.wxs or elsewhere, add a ComponentGroupRef to one or more Features.

Wix bootstrapper uninstall shortcut

I am trying to create shortcuts to uninstalling whatever the bootstrapper has installed.
So simply i want to do the same thing as the uninstall does when going to Add and remove programs.
I found that de bootstrapper is installed in package cache{guid}[bootstrappername].exe
One of the msi packages that it installs also installs a shortcut to this bootstrapper /uninstall call.
However problem is that the GUID of the package is regenerated on every build. So i some how have to set it as
a msi property.
But i cannot figure out how to do this, seem to me that the GUID is not known during building but only after build is done?
is there another way to determine the location of the cached bootstrapper ?
If you are use Managed BA you can try this:
In your Bundle.wxs in chain with MsiPackage add MsiProperty like:
<MsiPackage SourceFile="Setup.msi">
<MsiProperty Name="UNINSTALLER_PATH" Value="[UNINSTALLER_PATH]"/>
</MsiPackage>
Somewhere in code (before call install action), you need set value for this variable like this:
Engine.StringVariables["UNINSTALLER_PATH"] = string.Format(#"{0}\{1}\{2}\{3}.exe", Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData), "Package Cache", Engine.StringVariables["WixBundleProviderKey"], ProductName);
Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) – path to %systemdir%:\ProgramData
Package Cache- folder name in ProgramData where installing bundle caching
Engine.StringVariables["WixBundleProviderKey"] – name of folder (guid) created by caching bundle
ProductName – name of your bootstrapper “exe”
And finally in your Product.wxs you can create shortcut usual way, but in “Target” attribute you need pass UNINSTALLER_PATH value and “Arguments” set ="/uninstall":
<Shortcut Id="Shortcut1" Name="Uninstall" Description="Uninstall" Target="[UNINSTALLER_PATH]" Arguments="/uninstall" WorkingDirectory="Programmenufolder" />
sorry for my english :)
You can determine the location using the bundle upgradecode you define in your bundle.wxs.
Use the registry path to windows uninstall location of your bundle
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall{upgradecode of your bundle}
or for 64 Bit OS
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{upgradecode of your bundle}
The value BundleCachePath contains the fullpath including your bootstrapper.exe filename to the package cache where your bundle is cached.
You can also use the value QuietUninstallString which contains the full quiet uninstall command or UninstallString to launch the uninstall in non quiet mode.

Wix 3.6 Burn: unmanaged custom UI

I want to package multiple MSIs into a single install package, hence I am using Burn from Wix3.6.
I want to have a simple user interface allowing to select which package(s) should be installed.
I understand the standard BA (wixstdba.dll) does not provide this functionnality and that I need to write my own BA.
I have been looking at project 'wixstdba' from the 'wix36-sources' package as an example of a C++ BA. To get started I have tried simply rebuilding the project and adding the resulting DLL to my Bundle as follows:
<Bundle
Name="$(var.ProductName)"
Version="$(var.ProductVersion)"
Manufacturer="$(var.VendorName)"
UpgradeCode="$(var.UpgradeCode)" >
<BootstrapperApplication SourceFile="wixstdba.dll" />
<Chain>
...
I succesfully built the Bundle:
light -ext WixBalExtension.dll -ext WixUIExtension -ext WixUtilExtension installer-v$(VERSION).wixobj -o installer-v$(VERSION).exe
candle -o installer-v$(VERSION).wixobj bundle.wxs -d"Platform=x64"
However, when I run the resulting .exe, nothing happens. No UI appears, no software is installed and no error message.
Any idea what I might be doing wrong?
When you run the .exe, it should create a log file in your system's %TEMP% folder. This should tell you if any errors are being encountered. The file name will be the product name (with spaces replaced with underscores). The easiest way to find it is to open a Windows Explorer window, type "%TEMP%" for the folder name, and sort by Date Modified desc. The top file is likely the right one.
It is likely that the bootstrapper is running, but when it attempts to load your code it is unable to load some dependency, or otherwise has some error. Hopefully, the log will provide enough hints for you to find the issue.
If you end up needing to add additional libraries/files to be used by your BA, add them to the bundle payload files, like this:
<BootstrapperApplicationRef SourceFile="wixstdba.dll" >
<Payload SourceFile="$(var.ReferencedProject.TargetDir)\file.needed.at.runtime" />
</BootstrapperApplicationRef>
This will place the file in the same folder as your unpacked BA at runtime.

Can a .msi file install itself (presumably via a Custom Action)?

I wand to construct an MSI which, in its installation process, will deploy itself along with its contained Files/Components, to the TargetDir.
So MyApp.msi contains MyApp.exe and MyAppBootstrapperEmpty.exe (with no resources) in its File Table.
The user launches a MyAppBootstrapperPackaged.exe (containing MyApp.msi as a resource, obtained from the internet somewhere, or email or otherwise). MyAppBootStrapperPackaged.exe extracts MyApp.msi to a temp folder and executes it via msiexec.exe.
After the msiexec.exe process completes, I want MyApp.msi, MyBootstrapperEmpty.exe (AND MyApp.exe in %ProgramFiles%\MyApp folder so MyApp.exe can be assured access to MyApp.msi when it runs (for creating the below-mentioned packaged content).
MyAppBootstrapper*.exe could try and copy MyApp.msi to %ProgramFiles%\MyApp folder, but would need elevation to do so, and would not allow for its removal via Windows Installer uninstall process (from Add/Remove Programs or otherwise), which should be preserved.
Obviously (I think it's obvious - am I wrong?) I can't include the MSI as a file in my Media/CAB (chicken and egg scenario), so I believe it would have to be done via a Custom Action before the install process, adding the original MSI to the MSI DB's Media/CAB and the appropriate entry in the File table on the fly. Can this be done and if so how?
Think of a content distribution model where content files are only ever to be distributed together with the App. Content is produced by the end user via the App at run time, and packaged into a distributable EXE which includes both the App and the content.
MyApp's installer must remain an MSI, but may be executed by a Bootstrapper EXE. The installed MyApp.exe must have access to both MyApp.msi and EXE is to be "assembled" at runtime by the App from a base (empty) MyAppBootstrapper.exe, which is also installed by the MSI, and the content created by the end-user. The EXE's resource MSI must be the same as that used to install the App which is doing the runtime packaging.
WIX is not to be installed with MyApp.
There can be no network dependencies at run-/packaging- time (i.e. can't do the packaging via a Webservice - must be done locally).
I am familiar with (and using) Custom Actions (managed and unmanaged, via DTF and otherwise).
Add an uncompressed medium to your wxs like this:
<Media Id='2'/>
And then create a component with a File element like this:
<File Source='/path/to/myinstaller.msi' Compressed='no' DiskId='2' />
This will make the installer look for a file called "myinstaller.msi" on the installation medium, in the same folder as the msi that is being installed. The source path above should point to a dummy file, it is only there to appease wix.
Edit: The following sample test.wxs demonstrates that it works. It produces a test.msi file which installs itself to c:\program files\test. Note that you need to put a dummy test.msi file in the same folder as text.wxs to appease wix.

Having one .MSI package launch another .MSI package from "within" itself is called a nested install, and it's bad juju (see Rule 20). Windows Installer has some global data that it uses to manage the current install, and it doesn't handle well multiple installs at the same time. For the same reason, if you start one install and then try to start another while the first is still in progress, you'll usually see a pop-up to the effect of "another install in progress, please wait until it's done".
You can have a program, usually called a bootstrapper (I think that's what you're referring to) which is itself not an install package, but which contains an install package (such as an .MSI or an .EXE) as a resource, possibly compressed. The action of the bootstrapper program is to extract/expand the resource to a file, commonly in a %TEMP% directory, then either launch the extracted .EXE or run MSIEXEC on the extracted .MSI. The bootstrapper can contain multiple resources and extract+install them one by one, if you need to install prerequisites before the main package. Or you can ship multiple packages as separate files, and have the bootstrapper execute/install them directly from the distribution media one by one, or copy them down to the target machine and run the series of install from there, or...
WiX itself does not get installed, no. It's a tool with which .MSI packages can be built. The WiX project has on its wishlist a generic bootstrapper program, but it hasn't been implemented yet. There are other bootstrappers available, e.g. this one.
You won't need a custom action -- in fact, since the bootstrapper isn't itself a Windows Installer installation package, "custom action" has no meaning to it. And, if you're familiar enough with CAs to know about managed/unmanaged/DTF, then you know enough to avoid custom actions whenever you can. (grin)
I think it's much easier for your bootstrapper to extract MSI file to some predefined location rather than to the temp folder. For example, to C:\Documents and Settings\All Users\Application Data\My Company\My Product Install Cache. After installation finishes bootstrapper would leave MSI file sitting there. If at some stage user decides to reinstall your product Windows Installer will be able to locate source MSI file.
Also, add path to this file to RemoveFile table so that it gets deleted on uninstall. You can use RemoveFile element in WiX for that.
So if I understand, then I think I would have the app create a transform (MST) that has the content files and apply that to the base MSI. I'm still not convinced that I understand though. :)
I'd configure the MSI cache path to a known location.
Then at runtime if you need to "edit" the MSI use VBScript or similar.
But still, I ask WHY!?!
I am also working on a way to deploy multiple MSI files. I have a bootstrapper.exe program that bundles the MSI files and runs them one at a time. This solves my problem for most cases.
The case it does not solve is GPO (Global Policy Object) distribution of the install. GPO requires a dot-msi file to run an install.
To do this here's what I did which almost solved the problem (but not quite). I put the dot-msi files in the file table of an installer and put my bootstrapper in the binary table and run it from a custom action inserted after InstallFinalize in the InstallExecuteSequence. Of course the bootstrapper won't be able to run other MSI's because the top level MSI holds the _MSIExecute mutex.
It was pretty easy to get a little further. I made the bootstrapper return control to the top level installer and continute. And then I added a WaitForSingleObject call to wait for the top level install to finish, and the bootstrapper can then continue to finish the install.
My problem is that the GPO installation happens at boot time and the top level install completes before the sub installers are done and GPO reboots the machine.
The toplevel install also returns a success status when the install may actually fail later on.
I'm still looking for a way to block the top level install from completing until after the bootstrapper completes.
