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 personnel or package vendor.
Some part of the package is corrupt or not able to register or unregister. As well, some components for .NET 1.1 are not present.
There are several possible solutions:
Make sure that all required updates for the solution are installed. For example, Altiris Integrated Component for Active Directory needs to have SP3 for Notification Server 6.0 and SP1 for .NET; if SP1 for .NET is not installed, this error can occur. To get .NET v1.1.4322 SP1, go to Microsoft.com and search for "NDP1.1sp1-KB867460-X86.exe"
Download the solution again. Make sure you delete the current setup files.
Look at the following Microsoft KB 891985 for information about this error during an uninstall.
