Could this work to sidestep Windows Installer Error 1500?
We too have seen the 1500 error at times and it most always seems to be tied to Windows Update in some form or another. There may be other causes, but for us it looks like Windows Update. It is annoying as Microsoft doesn't seem to handle it all that gracefully. The install seems to be OK until the turnover to the execute sequence. Then you get the error message. I would think they should detect that right up front, which is what I would try to do.
I was thinking of running a custom action to look for a TrustedInstaller process. If running set property and use as launch condition. This might help avoiding the annoying message and help users sort through the issue first - complete Windows Updates, reboot, etc.
If it bypasses this detection and still gets the error, then we can support and troubleshoot the registry entry cleanup, etc.
Just wondering if you think the TrustedInstaller detection might work. ??
Thoughts, pointers, guidance appreciated!
Thanks in advance!!
