Cannot install SE Free

I've downloaded Solid Edge Free 2D but when I attempt to install, I get this messagebox:

InstallShield DLL Custom Action
File 'C:\DOCUME~1\rhaggard\LOCALS~1\Temp\_is4A.tmp' can not be found. Make sure the file is on target system or installed already.

Looking at that directory, I do not see __is4A.tmp. Any ideas why installation fails?

Re: Cannot install SE Free

Before running the SE installation, .NET 3.5 must be installed. This can be downloaded from here:

If this link is not valid then simply search Google for ".NET 3.5 install" and you should find a download link very near the top.
