Error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personal or package vendor
The installation is aborted... What can I do?
There is a Microsoft page about this problem: http://support.microsoft.com/kb/891985 , but this trick doesn't work for me.
