Installshield installscript setup terminates after UAC prompt

Question

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*vc:\\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!

Answer 1

Installshield relies on win32 libraries. I had a similar case and below are the possible solutions

1)Please try to apply all the available windows updates.

2)Try to repair windows system files.Reference https://answers.microsoft.com/en-us/windows/forum/windows_10-update/system-file-check-sfc-scan-and-repair-system-files/bc609315-da1f-4775-812c-695b60477a93

3)Try installing the executable after creating new user account.
