Mylenium...Please let me know what kind of information you require. The system is Windows 7 Professional (64BIT). The end user has local administrative rights. "External Tool" interfering with the program? Can you please explain what sort of external tool would interfere with the program? This problem did not occur until the program was upgraded from CS5 to CS6.
As I stated above, I've seen other issues that fall in line with this problem in this forum as well as others. However, I have not seen any resolution to the problem.
