ERROR 1720 - Problem with Windows Installer Package
I want to install a new version of Ad Aware 2007 I have just bought and at the time of downloading it, it is trying to delete the older version of the program and I get the below error message:
Error 1720. There is a problem with this windows installer package. A script required for this install to complete could not be run. Contact your support person or package vendor.
I have tried to go to add and remove programs and deleted the old program directly but I still get the same error message. Any ideas? Thanks.

You can try to download the Windows Installer CleanUp Utility by searching it on the web to solve this issue.
