I have an Excel Add-in that uses a Wix (3.10) install script. The installation works fine for all versions of Windows. However, if a Windows 10 the user tries to remove the add-in through System | Apps & Features, it fails with "There is a problem with this Windows Installer package. A program required for this install to complete could not be run." Looking at the uninstall log, I see this:
Error 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: _BDF865EC_34B3_4B29_986C_98D6EC1A9807, location: C:WindowsInstallerMSI2FE4.tmp, command: /uninstall="C:UsersWindows10AppDataLocalmyCompanymyProductmyAddin.dll" /privileges=user
The action that it is balking at is this:
<CustomAction Id="_BDF865EC_34B3_4B29_986C_98D6EC1A9807" BinaryKey="adxregistrator_exe" Execute="deferred" ExeCommand='/uninstall="[TARGETDIR]$(var.myProject.TargetFileName)" /privileges=user' Impersonate="yes" />
However, if I re-run my installer and select 'Remove', it uninstalls fine. If I run the uninstall from a command line (using the msiexec command found in the registry entry for this product), it also uninstalls fine. If I use the 'traditional' Control Panel option Add/Remove Programs, it is okay as well.
Also:
- This only happens in Windows 10. Older versions of Windows are fine.
- I have replicated on several machines, including a fresh install.
- I have an older installer (a VS2010 Setup Project), the problem happens with that installer as well.
- I have tried with UAC at different elevations, no difference.
- I have tried changing the Impersonate setting to "no", no difference.
- I have tried changing the Execute setting, no difference.
- I have tried commands other than adxregistrator, no difference.
It seems to me that there is a problem with the new Windows Apps & Features app, but I have yet to find anything on the Microsoft forums. The only thing I have found is this:

I realize that this technically is not an issue with Add-in Express (I'm currently blaming Microsoft), I suspect that a lot of Add-in Express users may run into it due to the way Office Add-ins are installed. |

Hello Marc,
Please modify the installer so that uninstalling the add-in creates a log file in a location other than the default one, reinstall your add-in, try to uninstall it using System | Apps & Features and send me both log files. You can publish them here or send them to the support email address; see {Add-in Express installation folder}\readme.txt; in this case, make sure your email contains a link to this topic.
To find how to create a log file in a different location, see section Get details about add-in registration/unregistration, see the PDF file in the folder {Add-in Express}\Docs on your development PC.

Hello Marc,
Thank you for the log files. I've reproduced the issue using a VDPROJ-based installer. We are looking into the issue.

Hello Marc,
We think the issue belongs to Microsoft. It looks they start an installer with limited permissions so that it cannot run a custom action; in our tests, only unmanaged custom actions are affected.
