System Center Configuration Manager. :) No clue how it does it. I would probably look at the registry.

Product 1 is installed. Product 2 needs to be installed. Product 1 has to be uninstalled before Product 2 can be installed. Hoping to roll the MSI /x and MSI /i commands into one script. Does MSIEXEC have some controls for this? Or should I programmatically read the Event Log in a repeating loop until the successful uninstall event is posted. Or maybe scan the HKLM\Sofware***\Uninstall registry to see if Product 1 is still in there? Ideas of what might be the cleanest and most reliable? I feel like I'm missing something very obvious :-\ TIA, Sam ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com<mailto:listmana...@lyris.sunbeltsoftware.com> with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe ntsysadmin
