Hi, I recently purchased windows 64bit ultimate and can't install. I have an alienware ALX computer which I purchased a couple years back. I am a newbie at this, seriously need help or my vista ultimate will be useless. Please help!
Upgrade isn't an option... you must clean install. The Vista setup will back up your current user files in a folder called Windows.old. However, it's still a really good idea to back everything up before proceeding. There is no upgrade path from 32 to 64-bit.
