i downloaded a free version of windows 7 ultimate 64 bit and i want to install it, because currently i have 32 bit w7 installed but i have 4gb of ram, so i need 64 bit windows. i tried to install but i get this message : this version of this file is not compatible with the version of windows you're running. Check you computer's system information to see whether you need an x86 ( 32 bit ) or x64 (64 bit) version of the program, and then contact the software publisher.
How can i upgrade from 32 to 64 bits if it doesn't let me?
