Hi all, I used Windows Vista 32bit and upgraded to Windows 7 64bit ( also upgraded Ram to 4GB ). Now I'm having problems with Windows 7 cause of lacking of driver for my laptop ( Sony FZ4000 ) I want to go back to Windows Vista, but 64bit to utilize the Ram upgrade. My question is can I use the DVD I used to install Vista 32 bit to install 64 bit ( do they came in just 1 iso ) ?? ANother question is will my license in the back of the laptop works ?? ( it saids Windows Vista Home Premium, doesn't specifically said 32 bit or 64 bit ) Thank you
Your version of vista that came with your machine will only have x86 versions of vista you will need to download x64 version your key will work on both versions i would check your key against the versions posted in vista OEM SLP keys.
thanks urie for your help So I need to download 64bit version of Vista ( same edition, retail original version is fine ? ) I will check my key with the OEM key posted in here when I get home and work on it later today. Thank you
