Your question is very hard to understand: why do you need to kill msiexec.exe? It is what actually running your installation! — Yan Sklyarenko, Mar 02 '11 at 11:54
If your installation is crashing, the fix is not to kill msiexec before the crash - the fix is to fix your installation script. — Jeff Yates, Mar 02 '11 at 14:05
If you will kill msiexec then your installer will end as msiexec is used to execute an msi — Sunil Agarwal, Mar 26 '11 at 20:14

You can create an msi log file to determine which specific custom action failed during installation.

I would recommend not using

WScript.Quit

Instead, use

Exit For

for example.

If CMSS.exe and CAS.exe are not running, then set an msi property and then in your wxs file, specify a condition that checks the value of that property to determine if the next dialog should be displayed for example.
