Error 1325 during installation

I've created an admin image of SW 2008 SP 0.1. When my userstry and launch the install using the StartSWInstall.hta page, mostof them are presented with the attached error messages. The text ofwhich says "Error 1325.solidworks is not a valid short file name.". Sofar only one user has been able to install Solidworks 2008 usingthis method.

I did some searching and it looks like it could be a WindowsInstaller problem. I've tried the Windows Installer CleanupUtility,http://support.microsoft.com/kb/290301,but it didn't help.

Any ideas?SolidworksAdministration
