PCs have the most current wininstaller 4.5 (WindowsXP-KB942288-v3-x86), I installed the newest antivirus msi package with no problems, reinstalled WindowsXP-KB942288-v3-x86 to correct any problems with the installer, same results as below... there must be a problem with the Ad-Aware msi and Windows XP, these are 5 different Dell PCs so it's not a hardware issue, the results are exactly the same regardless of hardware...
I tried upgrading to Ad-Aware 9.5 on several different lab PCs, All PCs XP SP3 with updates (as of 08.25.11)
I tried to install Ad-Aware 9.5 using the downloaded msi package, it starts the uninstall using Ad-Aware 9.07 uninstaller, part way through an error message pops up, click retry, then cancel, OK, then finish, does not auto restart. Manually restart, run 9.5 msi package which then tries to unistall the 9.07 version, same error messages as above. Restored Ad-Aware 9.07.
Ran the Revo uninstaller using advanced features and removed everything related to Ad-Aware 9.07. Rebooted and started install for Ad-Aware 9.5 using the downloaded msi package, the install starts then ends in a Windows Installer dialog box appearing on screen. Restored Ad-Aware 9.07.
