MSIZAP - Windows Installer CleanUp Utility

After upgrading my network to ZFD 7.01 Hot Patch 5, I had a corrupted install of Zenworks for Desktop Agent on a machine that I couldnt upgrade or uninstall. I kept receiving the error -1722 "there is a problem with this windows installer package"

Eventually came across TID 10088429, which explains that this is simply inevitable on some machines when upgrading to ZFDAgent 7.0.1.4 (which is the latest version in Hot Patch 5). They reccommend using MSIZAP to blow away the msi info and let you install a new one without any problems.

I have to say that I am in love with MSIZAP aka Windows Installer CleanUp Utility, an invaluable little tool for dealing with naughty MSI's.

here is the KB Article on MSIZAP: http://support.microsoft.com/kb/290301
