Been trying to install Final Cut Studio 2, but my mac fails to read some of the disks. The bottomline is that I have never been able to make it all the way thru the install without it failing. I have gone in and deleted preference files, the application icon from applications folder and the receipts. On the new attempts to reinstall, it never asks me again for the serial number of the product.....so somewhere there have to be some more files. Been researching and trying all sorts of stuff, but can't seem to get rid of it 100% This has been driving me crazy since it takes about 6 hours to install My mac never seems to be able to read the Motion disc Was hoping not to have problems like this when I switched to mac. Been frustrating so far.
