I have an InstallShield InstallScript (no MSI) installer which basically works quite fine.
On a specific machine, the installer immediately terminates after the UAC prompt for elevated execution. What I expect is that the installer is loaded and offers to install the prerequisites.
What I have tried so far:
- Observed the task manager detail tab and saw that the installer is listed for a split-second, then is gone.
- Put a log message in the OnBegin() callback, but this is way too late.
- Deactivated virus scanners.
- Checked windows event logs -- no related record found
- Attempted to execute the installer with logging using /V"L*v c:\file.log" -- no log file is written
- Attempted to execute the installer with logging using /debuglog -- no log file is written
I have already spent days with the problem, and I don't know where to look for any hint what is going on here, not to mention how to fix the problem.
Anything that can help here is highly appreciated -- Thanks!
