i have seen this issue many times...i have 17 pcs i use my stardock account on ( not recommended, youll be constantly emailing stardock) but i do it only on my personal systems to test all the software accross a wide range of hardware and windows versions.... many of my clients see my system and want it on theirs.... i then have them buy a subscription, or at least the programs they want ( do i get a bonus for refferals? ive sold maybe 20 - 30 OD subscriptions) but i have seen the issues described above.... some solutions i know work...
Games for windows live - - - i have seen this cause errors more than once.... make sure it does not load in the background at startup, only when you play games, this also includes the office and windows live add-ins.
windows vista - if you use tweak vista, set everything back to default, install other programs, then reset your settings in tweak vista.
some third party programs and messengers on lower resource systems can cause errors in installation too.
some p2p and torrent programs have caused a few issues too....
hope this is of some help
