Christian,

of course, this has nothing to do with the installer at all. Is your own Clarion application UAC-aware?

If "c:\AnotherFolder" (not a protected Windows resource) works fine but the "Program Files" folder tree (a protected Windows resource) does not work, then you have a serious (UAC) issue in your own application ;-)

BTW, here is a very brief description of how to make an application "UAC-aware"

Does this help?
