Or better yet, just use the upgrade logic in the Windows Installer... unless of course you're trying to detect a non-Windows Installer package. In that case, then you really should use the mechanism the previous product suggests to detect it. If it is really to go walk around in the ARP registry keys, then I don't see anything wrong in the syntax... are you sure the registry key exists?

I was thinking of using something like this, but can't seem to get it to work. I most likely have the logic wrong in CDATA. <Property Id="PACKAGE_INSTALLED"> <RegistrySearch Id="REG_FOUND" Root="HKLM" Key="SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{xxxxxxxx-xxxx- xxxx-xxxx-xxxxxxxxxxxx}" Name="ProductVersion" Type="raw" Win64="no" /> </Property> <Condition Message="Package X is installed. Please uninstall it before trying again."> <![CDATA[(NOT PACKAGE_INSTALLED) OR REMOVE]]> </Condition> Any advice is appreciated. -- Harvey Werner ------------------------------------------------------------------------- Using Tomcat but need to do more?
