I have a custom wix burn installer that I have made and it works well except for I can't figure out how to do one thing: save the wix burn installer exe to a location after the installation is done.
Here is my scenario:
My software can be distributed across multiple servers, but one server is the "core" server.
I plan to update the core server and then have the core server push software updates to the other server.
To have the core server distribute the update, it has to keep a copy of the Wix Burn Installer EXE somewhere for distribution. This is what I can't figure out.
Using the built in variable WixBundleOriginalSource, I can find the original installer exe. However, when I try to copy it during ApplyComplete (I don't want to save it unless it successfully installed), I get an access denied trying to copy the file (which makes sense since the burn installer is not running as an admin).
How can I accomplish this - copy the original wix burn installer exe after the installation is complete without permission issues? I get that 99.99% of the time, all file operations should happen inside an MSI, but I can't have an MSI deploy the original Wix Burn Installer, so I am stumped.
Ideas?
Thanks.
OK - here is how I worked around it. I passed the WixBundleOriginalSource to one of the MSIs and then added a CopyFile element to do the copy in the MSI...
Copy file from setup location to another location in wix on install

I have an app with an existing autoupdate mechanism, that includes a fail-safe: if the installation fails, it uses the old .msi file to restore the old version. The update procedure finds the old .msi file in the \Installer directory.
I recently updated installer generation to use WIX. Now, when the app is installed, the .msi file is not copied into the \Installer directory, all that is created is a file called wix{}.SchedServiceConfig.rmi.
I tried perfecting the WIX installer, using its transacted nature, so that if the installation fails, the installation transaction would be rolled back, and the old version restored - but for some reason, most of the time, when the installer fails, I end up with the app being wiped.
I tried finding the .msi file used for the install in other locations, so that the auto-updater can re-run the installer in case of a failure, but I can't find the msi copied anywhere.
Any ideas how
a.) an installer created with WIX can be authored to be fully transactional?
or
b.) where to find the msi after the installation?
I am trying to find any information how the Windows installer cache is working for Wix Bootstrappers.
For MSIs you do not follow any special rules to be sure a MSI will be cached by Windows. For Bootstrappers (Burns) it looks the same, but I had several issues trying to uninstall the package without original installer.
For me several points are not clear:
how to uninstall a product without original .exe installer?
will .exe installer be cached by default during installation?
does custom user interface affects Windows caching rules for .exe installers?
If you go into your registry and find "Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall", you should be able to find a registry key corresponding to your installer package. There should be one for the bundle itself and one for each .msi installed as part of the bundle. If you find the correct key for the bundle, it will have a value called "UninstallString". This is the string you should use to manually uninstall the package via the command line.
For your second point, Windows automatically caches installed burn bundles. The same registry key you found in the step above will have another value called "BundleCachePath", which should point you to the location of the cached .exe file. This should be under "C:\ProgramData\PackageCache{GUID}", where {GUID} is the package GUID of the bundle.
I can't see why having a custom UI would change the caching location, unless you manually add a dialogue to do so.
I'm looking to create a Windows Installer package that will run an exe that runs another Windows Installer.
I'm putting a package together that has to install three files, an EXE, a CONFIG and an empty TXT. In addition, we also need to run the Access Database Engine 2007 as part of this process. However, when setting custom actions to just run it (with the flag /quiet) it fails because it's attempting to run an MSI inside of an MSI.
Is there any way I could somehow have it launch right after/right before or something? I've looked into WIX but honestly I'm clueless on how it would solve the problem.
Thanks.
You should look at the WiX Burn functionality and prerequisites. Some examples are:
WiX - Install Prerequisites and 3rd party applications
http://www.c-sharpcorner.com/UploadFile/cb88b2/installing-prerequisites-using-wix-bootstrapper-project-and/
You could probably just run the setup from the Burn bootstrapper - it will do its own detection if it's already installed.
I created one msi for my product it's working well but I need to install .net 4.0 as a prerequisite. I came across burn and bootstrapper but have a couple of questions:
Should I have a separate project for the main msi and the bootstrapper?
My customer needs an msi (not an exe), so can the bootstrapper be an msi?
The bootstrapper project is a separate project and produces an .exe as its output. It is its own executable, whereas an .msi is essentially a database that gets processed by Windows Installer.
MSI (Windows Installer) does not support "nested" installs, where one .msi package runs for a while, then pauses, runs a separate installer package, then picks up from where it paused. MSI uses some Windows resources that are essentially system-global, so the "inner" install tromps on the "outer" one.
The way to do multiple installs as a single user experience is to run each install in sequence, one at a time. That is the purpose of the bootstrapper, also known as a chainer: to run the chain of installs, link by link. The bootstrapper is not itself an install package; it is a tool for running one or more install packages.
That is why the bootstrapper cannot be an .msi: it is not itself an installer package. A bootstrapper can be as simple as a batch file or script, or you can use an industrial-strength tool such as a WiX burn bundle, Flexera AdminStudio, etc.
Be aware that there are some installer packages that ship as .exe -- for examples, the .NET Framework or SQL Server installers. These are essentially self-extracting archives that contain one or more .msi packages, dump a temporary copy of that payload then run the Windows Installer service on it. In some sense they are "bootstrappers" plus package, all rolled into one. A bootstrapper can run packages (and other bootstrappers), but not vice-versa.
You might think that you could have your outer package run a custom action that launches the inner package. We've all tried it... and found out the hard way that it doesn't work generally, even when you appear to get away with it on some specific target system.
You'll have to persuade your customer that Windows Installer does not, cannot, work the way he thinks it does. Sadly, sometimes the only way to do this is to replace the customer.
I've developed a Wix installer for an internal project however entirely by accident I've found that I'm unable to uninstall the installer on my development machine as I get the following error message:
The feature you are trying to use is on a network resource that is unavailable
with a dialog pointing to the path of the .msi that I installed from feature from. (The .msi is there, however is has been rebuilt and so has changed since I installed it)
I'm concerned by this dialog as I had believed that Windows Installer kept track of installed .MSI files, however this dialog seems to suggest that I can break my uninstaller by deleting, moving or changing the installer.
Is this the case?
What do I need to do to make sure that I don't break my uninstaller in this way? (Do we need to keep copies of all versions of the installer ever installed on a machine?)
The easiest way to get out of this situation is to do a recache/reinstall. Build a new version of your MSI that isn't "broken" (in whatever way it is broken, in this case, it might not really be broken at all, you just need a new source). Then you use a command line like:
msiexec /fv path\to\your.msi /l*v i.txt
That will copy your.msi over the MSI that is cached and do a repair. Then you'll be in a better place.
One of the first painful lessons of writing installs is to never run your install on your own box. Certainly not until it reaches a point of maturity and has gone through several QA cycles. This is what we have integration labs and virtual machines for. (There is a saying about things you shouldn't do in your own back yard.)
That said, normally an MSI uninstall doesn't require the MSI but there are situations where it could be required. For example if one was to call the ResolveSource action during an uninstall, MSI would then look for the .MSI.
Now there are several ways out of this pickle:
Take an MSI you do have and edit it with ORCA to match to file name, UpgradeCode, ProductCode and PackageCode of the MSI that you installed. You should be able to get all of this information from looking at the stripped cached MSI that exists in %WINDIR%\Installer. CD to that directory and do a findstr -i -m SOMESTRING *.msi where SOMESTRING is something unique like your ProductName property. Once you know the name of the cached MSI, open it in Orca to get the required attributes. Then put these attributes in a copy of the MSI you have available and try to do an uninstall. No, it's not the exact MSI that you installed but usually it's close enough.
or
Use the front end windows installer cleanup utility (if you still have it) and/or the backend MSIZAP utility to wipe all knowledge of the application from MSI and Add/RemovePrograms. Note, this doesn't actually uninstall the program so you'll have to also write a script or otherwise manually uninstall all traces of the program.
or
Reimage your workstation
If you know exactly what is wrong (which is often the case during development), I prefer to open the MSI file that Windows will use for uninstallation and edit it directly with a tool like Orca to fix or remove the part that causes the failure.
For example:
Locate the MSI file in %WINDIR%\Installer. The MSI should be the last edited MSI file in that folder right after you did the failed uninstallation.
Open the msi file with Orca.
Remove the failing part - for example the InstallExecuteSequence action that fails which is atypical scenario.
Save the msi and close Orca to release the lock on the msi file.
1 - Have you experimented with "run from source" during installation?
This is an option in the feature tree which allows you to run some files from their installation source. This is generally combined with an admin image on the network. See image below. I haven't tried it, but I assume this could cause: "The feature you are trying to use is on a network resource that is unavailable" if the network is down and you are trying to uninstall. Just a theory, there are other ways this could happen.
2 - Are you running script custom actions? If so, do you extract to the tmp folder or run from installed files or the binary table? If so, is the custom action conditioned to run only on install?
3 - Are you perhaps running an EXE custom action that is pointing to an installed file? If so this file may be unreachable on the network.
4 - Are any of your userprofile folders redirected to a network share?
5 - Are you installing anything directly to a folder on the network?
There are plenty of other possibilities.
