Windows 7 and Vista Activation FAQ: How do language, version, 64-bit or 32-bit, and source affect ability to install and transfer Windows licenses?
I have windows 7 ultimate 32 bits, but I need to install some programs by Adobe that requires 64 bits version. Is there any way I can upgrade to 64 bits with no new installation? Because I don't want to upgrade all my files and get through all that long process installing all again. Unfortunately I don't have the time too.
Thanks in advance.
