@Sandher: Yes, this is the approach I am testing right now, and it seems to work fine.
@Blair: Interesting. Definitely somewhat easier than searching for a registry key. Thanks for both suggestions.

Subject: Re: [WiX-users] How do I check for existance of other installation In most cases you would check for the existence of something the primary product installs such as a Registry Key or a File Version. This is how the .NET Framework checks in WixNetfxExtension work AFAIK. I use Properties with RegistrySearches in our plug-in installers to check for the existence of the app the plug-in is for and the existence of our software. You can then use those Properties in LaunchConditions or Feature Conditions to either disallow installation entirely in the first case or selectively disable/remove Features if you have Features which depend on the primary product existing in the second case. Works pretty well for us so far.

This project however depends on the existence of our primary product. So, basically I have to test for the existence of our primary product, and if it is not installed, abort the installation. How do I do that? Is there some kind of support built into MSI, or do I simply solve it by having the primary product create a key in a known location in the registry? If this key exists, then I can proceed with the installation, if not abort.
