I think your problem is due to using Level="0". See -> http://msdn.microsoft.com/en-us/library/aa369536.aspx
Personally I would recommend you don't set your property to anything to start with, simply use RegistrySearch to set it (so it will be null unless your RegistrySearch is successful) & change your condition to: <Condition Level="1"><![CDATA[FOUND_VC80DIR OR Installed]]></Condition> as well as changing the Feature's Level to 9999 (or higher if you use INSTALLLEVEL's as high as 9999 & above but 9999 should be high enough for most people). This should make it only install if the FOUND_VC80DIR has a value set & should make it always uninstall. Works for me in 3 (or 12 depending on whether you count the supported applications individually rather than the features it's implemented in) almost identical situations to this. Good Luck.

I search the registry for a particular value to indicate if it is present or not, and set this value to a property called FOUND_VC80DIR, which initially has the value of "UNKNOWN". On my feature I have this condition: <Condition Level="0"><![CDATA[FOUND_VC80DIR = "UNKNOWN"]]></Condition> I'm trying to work out how to get my product to uninstall after the user has removed Visual Studio. I install my product, remove the VS value I reference (to simulate an uninstall without actually having to sit through it) and then uninstall my product. The product is uninstalled but it leaves behind the files from this feature. I tried adding "AND NOT REMOVE" to the condition, but this only seems to work if if I uninstall it by using the "msiexec /x" from the command line. If I go through the UI and choose to remove it then I am still left with the files. Can anyone let me know how to get round this?
