So I'm trying to install Studio 15 Ultimate on my computer. This is the third time I'm installing it. I've had it installed on previous windows installations. Previously it has worked normally. Now I'm getting "data1.cab is faulty and cannot be used." I'm using the same windows 7 as always and the DVD is without a scratch. What can I do? I need this for my work.

Can you copy the files from the DVD to an hard drive ?

For some reason I never thought that would work, but it did. I managed to install the program. There were some hiccups, though. Apparently some plug-ins weren't installed because the program was already running and when I try to activate (again) my mpeg4 decoder/encoder, it says that key has been created for different passport. I used the same email when I reregistered during installation. I might have put a different name there, does that matter? Edit: it seems I have a different pass now. Here's a link to our older discussion: http://forums.pinnaclesys.com/forums/thread/662825.aspx

PM me your new passport # + registration email address. I'll ask a key to Corel for you.
