I am confused that you installed from a thumb drive. What did you do, move files over in sections with a thumb drive because that is a LOT of data to be moving in small chunks. It might have been a better plan to put that computer on your home network, but not on the internet, long enough to copy all the files in a peer to peer configuration from the a shared drive on the computer where you did the d/l to the one you want to install it on.

Then reinstall when you have all the files moved. I have never heard of anyone having problems just getting the thing installed. I am among the large number who had trouble at first with the learning curve, but installation, particularly from the external hard drive, was a snap. Updates all went smoothly as well.
