i recently bought a lenovo u450p laptop/netbook. although it i great, it had a problem. it has 4 gig's RAM but came with 32 bit windows. kinda a waste since i bought it for the 4 gig's RAM. but after some research i found out a license will work for 32 and 64 bit. ah, i thought, i will get the file's do a clean install, type the key and all would be good. not. i installed 64 bit, fresh, but now it keeps telling me that 'the key i typed is invalid for the action' i have already tried a lot but nothing seems to work
*i deleted old windows file's
*i installed all updates
*i disabled AVG firewall
and so on
there is no such thing as pirated file's. license's are pirated, file's aren't, they are legal to download and use(well, that is what i was told, and read on multiple forums). they were distributed by Microsoft, once, and passed on to other site's.
anyway, if OEM license's won't work for retail, then i guess that is the problem... never imagined that OEM file's were different from retail
Note that you will almost certainly want to use a Lenovo OEM disk rather than just any OEM disk. And don't bother with downloadable ones that you find on torrents - Microsoft blocked the keys for these Lenovo OEM images a long time ago.
Anyway, if your 32-bit Windows 7 has already being activated then I wouldn't count on your being able to now use that key to activate a 64-bit installation. Microsoft have already recorded that key as being associated with a 32-bit installation. If it was a retail version you'd be OK, but OEM is limited to (essentially) one-time installation and possible re-installation of that original setup.
