I installed pre-RC1 64 bit and it worked really slick. Decided to clean \ninstall build 5728 and it is nothing but trouble and won' t upgrade. This is \nin a dual-boot pc.\n\nI have an Intel dual core with a gig of memory, using onboard video. The \nguy is not a power user so it is adequate. Device manager is not listing the \naudio or specific video drivers and won't let me install the 64-bit drivers \nfrom Intel. I was really impressed with the way it was running with the \nearlier build but thought it might be too buggy for him to use. And I missed \nthe 64-bit RC2 download. I caught the 32-bit only. \n\nWould it be better to put the RC2 32 bit os on it instead because I think \nthat one is pretty stable from using it on a few other pcs?
