Hi again,
Thanks for responding.

The problem seems more complicated than just a permission issue (btw, I'm using windows XP).

I have a medium sized setup project (called "Darwin Setup") which compiles fine. I can compile it any number of times. I have a larger project (one that makes a backup of the whole Clarion6 folder) which gives me the error.

After I try to compile the "clarion6" project, SetupBuilder no longer is able to compile the "Darwin Setup" project giving the same error. If I close SetupBuilder and reopen it, then I can compile the "Darwin Setup" project again.

Any further ideas?
