Your ASPNET user account very likely does not have permissions to your Window's temp folder. You should create all temporary files within the webroot of your application.

I've never used Crystal Reports (as a PostScript/PDF coder, I create reports directly when needed), so this advice might be off-base: is there an object you need to "close"? If the file handle is still being controlled by some class/method/object in your program, you might not be able to access it. Make sure you do all the necessary housekeeping tasks.

u were right, i changed the folder and i managed to export the file.
thanks again
