While attempting to install the User State Migration Toolkit on a Windows Server 2008 system, you will be presented with an error stating that “There is a problem with this Windows Installer package. A program run as part of setup did not finish as expected. Contact your support personnel or package vendor.”

This problem has been noted on the USMT team blog.

When you click the OK button on the error message the USMT301 folder will be erased. However, as a workaround to obtaining the source files to build a USMT package for operating system deployment with Configuration Manager, you can keep the error message up, copy the source files from the C:\Program Files\USMT301 folder to another destination. Just make sure to do this prior to clicking OK. Otherwise, they’re gone!
