Er...you may want to put a big warning sign on or immediately preceding the download page for the Measurement Studio Eval. This is a *nasty* problem, as indicated by the posts above; if you're aware of it, you should make your customers aware of it, too, before they get blindsided. I know that my gut reaction on seeing this problem was "dammit, I'll never try out an NI product again". Glad you found a fix, though.
