I can't install either for the apparent same reason:
23:25:07 min/gen Return code: 0x20000021 [You can install avast! only after the hotfix KB816542 is installed.
Use Windows Update or download it from Microsoft's website.]
23:25:07 min/gen Stopped: 23.05.2010, 23:25:07
I wonder why I receive that message since my OS was recognized as XP sp3

Besides, Microsoft states that KB816542 is meant for Windows 2000, the functionality is supposedly integrated in XP

Can someone help me? Thank you in advance.
