[wix-users] failing to elevate privileges on Win 10 - WiX 3.9r2

[John Cooper]

Is FileVirtualization disabled?  I've seen some crazy configs where UAC is on but FileVirtualization is disabled.

The e-mail below is from an external source.  Please do not open attachments or click links from an unknown or suspicious origin.

winerror.h 0x80070020
#define ERROR_SHARING_VIOLATION
The process cannot access the file because it is being used by another process.

Kind of sounds like the attempt to create an elevated process failed due to some crazy anti-virus software.

Hi,

I have a colleague running Windows 10, testing my application.  When he tries to install my application he does NOT get a UAC prompt, the installer fails, and the log file includes this:

[190C:5294][2016-09-28T17:43:56]e000: Error 0x80070020: Failed to launch elevated child process:
C:\Users\Dan\AppData\Local\Temp\{91da9c8a-d362-4609-be08-5f648f4ee8fe}\.be\MapCreatorSetup-x64-1.5.0.exe

[190C:5294][2016-09-28T17:43:56]e000: Error 0x80070020: Failed to elevate.

[190C:5294][2016-09-28T17:43:56]e000: Error 0x80070020: Failed to actually elevate.

[190C:5294][2016-09-28T17:43:56]e000: Error 0x80070020: Failed to elevate.

If he right-clicks the installer and selects Run as Administrator, he gets the UAC dialog, clicks Yes, but does not have to enter his password.  Then my installer works.

His experience is identical whether he tries to install with his admin user or his non-admin user.

His UAC Settings are set at the default, second from the top (“Notify me only when apps try to make changes to my computer (default)”).

I’ve tested on 3 other Win 10 machines and cannot duplicate the problem - my installer works as expected.  Any idea what could be causing the problem on this one Windows 10 machine?  My fear, of course, is that when I release my app lots of other people will have this problem.

Thanks,

David
