Application crashes if installed in C:\Program Files

Hi

I've created an application that crashes with a Vista error messag
when it's installed in C:\Program Files(the default location). If I jus
copy the application folder into, say, C:\, it works. The applicatio
also works flawlessly in XP. I'm guessing this has something to do wit
the fact that Vista doesn't allow write access to C:\Program Files? Ho
can I get the application to work? From what I've read online, Vista i
supposed to transparently relocate the files t
C:\Users\username\AppData\VirtualStore\Program Files\My Application\ bu
this doesn't seem to happen since it crashes

My application works if I run it as administrator btw. It's built wit
Visual Studio 2005 with the Vista SP1 update

Thanks
