SYMPTOMS
After you encrypt resources by using the PACE Anti-Piracy InterLok system on a Windows Vista-based computer, some applications may work incorrectly. This problem occurs if the applications access the encrypted resources.



CAUSE
This problem is caused by a security design change in Windows Vista. In Windows Vista, the Windows System Resource Manager (WSRM) validates the data structure more thoroughly than in Windows XP.



RESOLUTION
A hotfix is available to resolve this problem. After you enable the hotfix, the hotfix turns off the validation for some specific processes. Therefore, the applications can work correctly. However, after the validation is turned off, these specific processes become vulnerable to attack by corrupted files. Also, these processes may load encrypted resources that are not valid.
