Summary

Symptoms

Using the command line setup.exe /d, as specified in the Help Library, does not launch the InstallScript debugger.

Reference: Setup.exe and Update.exe Command-Line Parameters

Cause

The setup.dbg file may be missing or in the wrong location.

Resolution

1. Copy the InstallScript debugger executable ISDbg.exe (located in the System folder of your InstallShield DevStudio or Developer distribution) to the test system, and register it by launching the executable with the /REGSERVER command-line argument.
2. Copy Setup.dbg to the test system.
3. Run Setup.exe with the command Setup.exe /d"<PATH>" where path is the directory containing Setup.dbg. For a Basic MSI project, the command:

   Setup.exe /v"ISSCRIPTDEBUG=1 ISSCRIPTDEBUGPATH=\"path-to-Setup.dbg\""

   runs your InstallScript custom actions in the InstallScript debugger.
   
   
   With an InstallScript MSI project obtain for reference the file "Setup.dbg" from the directory "Script Files". The *.dbg should should be built and exist next to your setup.rul.
   
   Set ISSCRIPTDEBUG and ISSCRIPTDEBUGPATH and expect the InstallScript debugger to launch. Expected to work using New Style or Traditional style ISMSI
