guid not found

I downloaded the trial version. Used the setup.exe to install. All files were (afaik) properly installed. However upon linking a sample i got:

E2501 Unable to open import file 'libid:7A3A786C-EB8C-43b3-BC10-8D09ACF5D195'

How to progress from here?

Can't you generate a TLB? That would make things so much easier.

What sample are you looking at?
