I just purchased 2 new computers, one for my wife and one for myself. They are basically the same,---Windows 7, 64-bit; AMD A8 quad core w/ 4GB ram. I installed my BIAB 2009.5 from my discs, then installed my BIAB 2012 upgrade,---all went well on my computer. When I tried to install it into my wife's machine (which is the one I use when we travel), 2 of the disks would not load correctly (RealDrums 1-6; and one of the Realtracks discs). They just come to a dead stop on a file and give me the option to retry, abort or skip. Retry did not work, I just hit skip. It would begin loading for a few more seconds, then hit another file that did the same thing. This went on from file to file,---any idea why the install went well on one machine but not the other? Thanks in advance!
