Hi Mike,

Just want to point out that "VCXNAME" should include the extension ".VCX". The code might still cause problems if for some reason the user installed the application in a folder that happens to contain the VCX name. Not likely, but hard to trace down when it does. And it's one way to force an application into an error if you need to bypass some security measures.
