Standalone WIX uninstaller - wix

I'd like to create a standalone silent uninstaller using WIX that I can send to specific people for support purposes that can be double-clicked to execute the uninstall of our product when the uninstaller did not work properly on their machine and no longer exists (some users remove things manually using other tools). I have a .wxs file that uses the same product id and package id of the previously installed program, and if I run from msiexec /x it uninstalls the previously installed product perfectly. Double-clicking on it (which is all these users can be expected to do) however runs installation, not the uninstall. I tried adding
<Property Id="REMOVE" Value="ALL"/>
<Property Id="ACTION" Value="UNINSTALL"/>
and making sure all InstallExecuteSequence actions are not using an "Installed" check but the product is still installed after running successfully, the log file shows it is still executing ACTION INSTALL:
MSI (c) (A8:F8) [15:42:08:324]: PROPERTY CHANGE: Adding ACTION property. Its value is 'INSTALL'.
MSI (c) (A8:F8) [15:42:08:324]: Doing action: INSTALL
MSI (c) (A8:F8) [15:42:08:324]: Note: 1: 2205 2: 3: ActionText
Action 15:42:08: INSTALL.
Action start 15:42:08: INSTALL.
Is there a way to force an .msi file to perform an uninstall without using the command line or add/remove programs entries? I've seen entries about using ARPSYSTEMCOMPONENT but not enough information to do it.

I don't think so. You could, of course, use an exe to do it. I would also strongly suggest that you use the original msi file instead of creating a different msi with the same product code.
For the exe, you could use any number of chainer/bundler/downloaders. There is NSIS and also WiX's own Bootstrapper, ... even WinZip.
You should also note that many package management systems that run uninstall commands will run the install command first if anything is amiss. The theory is that an uninstaller can't properly run unless the critical data placed by installation exists. (E.G., WPKG). For Windows Installer, this usually doesn't apply since it's data is hidden from the user. But if they found it and corrupted it, reinstalling and/or repairing using a fresh copy of the original msi might do the job.

Why would a WiX installation create two entries in HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\

I'm trying to uninstall an older version of our product which was installed using a WiX-built installer and after uninstalling it silently:
msiexec /x{GUID}
the program still appears in Control Panel. I've opened a separate item to
explore that mystery, but another curious issue has popped up. I noticed that after running the install for this program, two entries (GUIDs) are added to HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall. One with the product GUID and one that I have no idea where it comes from. I've searched through the .msi and it's not in there. Both are created each time I install, both are removed if I uninstall from the Control Panel and both are left in the registry if I uninstall from the command line. So have a look
Anyone have any ideas what's going on here?
Embedded Setup.exe: In essence it looks like you are installing an MSI that also installs an embedded non-MSI setup.exe via a custom action as part of its own installation sequence. Or, there is a setup.exe launcher that kicks off the MSI and the legacy setup in sequence. Result: two entries in Add / Remove Programs.
Uninstall: It is obvious, but to get rid of the second entry you must run its uninstall sequence - in addition to the uninstall of the MSI. Non-MSI setups are less reliable when it comes to uninstall than MSI packages. The implicitly available uninstall for all MSI packages with reliable silent running is one of the core benefits of MSI: MSI Core Benefits (among other topics).
Uninstall Commands: Try running the silent uninstall string, I guess that is what you have done?
Run commands elevated! With admin rights!
REM Uninstall MSI
msiexec.exe /x {PRODUCT-GUID} /L*v C:\MySetup.log /QN
REM Uninstall legacy setup.exe
"%SystemDrive%\ProgramData\Package Cache\{c5f0cb3e-1de3-4971-843a-abb981ed670c}\MDRSetup.exe" /uninstall /quiet
Silent Running: To run legacy setups silently you sometimes have to record a "response file" to record all settings in the GUI and pass to the uninstall process. I have some previous answers on this. You also need to run with admin rights:

Application Repackaging: What is the name of the software you are installing? MDRSetup.exe, is that Max Data Recovery 1.9? Probably not. Getting rid of legacy software can be challenging. You can always try to re-package it as an MSI if you have the tools to do so, or maybe you have a team in your company to do so (all large companies tend to). Not all legacy setups can be repackaged. There could be constructs that are impossible to capture, such as certain drivers, generated and unique keys per machine etc...

Is there anyway to upgrade a .exe installed program with .msi without a double entry in ARP?

I am currently using WiX Toolset to build my installer. This tool is very nice but recently I encountered a problem. When I installed my program with .exe, then upgrade it with .msi, there is a double-entry in Add/Remove Program. Is there anyway to prevent the installer add double entry? Thanks!
It's not clear from your post if you have followed the rules for a major upgrade, such as use the same UpgradeCode, new ProductCode and PackageCode, increment ProductVersion in the first three fields, have upgrade logic in place in the MSI (such as major upgrade element). You'd need to supply your WiX source for these in the old and upgrade builds to see the differences. A verbose log would also help, installing the MSI with a command line that includes /l*vx [path to log file]
If those rules have been followed, the main reason for failure to upgrade is the one was per user and the other is per machine (or vice versa). One context will not upgrade the other. If this is the case the log will have an entry somewhere with FindRelatedProducts referring to an installed product in another context.
All this also assumes that the original install you did was MSI-based underneath the exe. If it was not, and it was some other install software that is not using an MSI file then there is no such thing as an automatic upgrade. You'd need to find some none-MSI way to uninstall the older product. A typical way is to find the UninstallString in the registry for that product and run it. Depending on the software used, that command can be parsed to add a silent option.

How to update Windows installer package over installed msi with same product id

I have created a wix installer project which is working fine. It installs my application on system easily. whenever if there is any change in any file or service, i uninstall msi from controk panel and installs new msi on system.
But whenever i install new msi, application's all setting change after new installation, that doesn't sound good. For sort out this, i am using Upgrade code in Product.wxs file. But when i install new msi after build, but is shows given error:
Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel
So, i want to update windows application package whenever there is any change in files and with same Product id. I just want to update installed msi, dont want to remove that.
You cannot use the same ProductId to do upgrades, you need to change it. The best way is to set ProductId="*" and this will change it for every build. You will also need to increase the version number and this best done by using the main exe assembly version number. See http://wix.sourceforge.net/manual-wix3/major_upgrade.htm for more info.
You can use the same ProductCode to update an installed MSI. Basically you increment the ProductVersion, rebuild the MSI (with new PackageCode) and do a minor update with a command line such as:
msiexec /i <path to new msi> REINSTALL=ALL REINSTALLMODE=vomus.
In my experience this not commonly used because if you're going to rebuild the MSI you may as well upgrade with a major upgrade.
If all you want are updates to a few files and you're not ready to ship a complete MSI file, then that's what patches are for. Rebuild the MSI as above, then build a patch - the patch is the delta between the two MSI files, see docs for MsiMsp.exe.

Wix / MSI : Unable to uninstall

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.

WiX: Forcefully launch uninstall previous using CustomAction

I'm writing a new major upgrade of our product.
In my installer I start by finding configuration settings of the previous version, then I'd like to uninstall the previous version.
I have found several guides telling me how one should make a MSI suitable for such upgrades.
However, the previous was not an MSI.
It was not according to best practices.
It does, however, in registry HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall{GUID} specify an UninstallString.
Using a RegistrySearch I can easy find the command below, which I store in UNINSTALL_CMD.
RunDll32 C:\PROGRA~1\COMMON~1\INSTAL~1\PROFES~1\RunTime\10\01\Intel32\Ctor.dll,LaunchSetup
"C:\Program Files\InstallShield Installation Information\{GUID}\setup.exe"
-l0x9 -removeonly 4:
I cannot get the hang of the CustomAction needed to perform the actual uninstall.
<CustomAction Id="ca.UninstPrev" Property="UNINSTALL_CMD" ExeCommand="" />
The MSI logs says:
Info 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor. Action: ca.UninstallPrevious, location: RunDll32 C:\PROGRA~1\COMMON~1\INSTAL~1\PROFES~1\RunTime\10\01\Intel32\Ctor.dll,LaunchSetup "C:\Program Files\InstallShield Installation Information{GUID}\setup.exe" -l0x9 -removeonly, command:
Anyone seeing what I am doing wrong here?

I did application repackaging for a couple years at Continental Airlines where I did SMS pushes to an 18,000 seat forest. I frequently had a legacy application in the wild that was not installed using MSI that I needed to get redeployed using MSI and once that was done I supported major upgrades going forward.
These previously deployed apps typically had very broken and misbehaved uninstallers. Instead of calling these, I would use SMS to query the forest to get all the deployed versions. I would then deploy those old packages to a integration lab and work out what it was each installer did to the machine and write my own aggregated "forced cleanup" custom action that was capable of wiping the various versions of the application off the machine.
I executed this custom action prior CostInitialize so that when the new MSI did it's costing it wouldn't be influenced by the crap that was no longer on the machine. This worked for me because I pushed packages as System and I didn't have to worry about elevation issues. If you want to be fully UAC compliant you would want to run this custom code from a prereq package and either have your users run it manually or wire it into a bootstrapper to run prior to your MSI.
After a good nights sleep I found my error.
If you really read http://wix.sourceforge.net/manual-wix3/wix_xsd_customaction.htm the answer was there.
I was trying to make a type 50 custom action, launch an executable already installed on system.
Property specifies the full path to an executable to launch
ExeCommand specifies the command line arguments for this executable above.
And my fault was that I did place the full exe+command line in the Property field.
