Great Plains is set up on several users computers. The interface includes shortcuts to several Crystal Reports. After installing ACT, the shortcuts to Crystal Reports are displayed with an ACT icon, and when clicked it appears that the shortcut is trying to use ACT to open the file instead of Crystal Reports. It doesn't look like I have the abilty to change the program in the shortcut to Crystal Reports. I had to uninstall ACT to get the reports to work correctly in this interface.
