Help please!!! More about : upgrade bit bit windows clarkjd May 25, 2013 3:16:45 AM Windows is saying that it can't find a driver for your DVD drive(probably a 64-bit driver). Check the manufacturer's website to see if they supply a 64 bit driver. If not, you may have to get a new DVD drive. mbarnes86 a b $ Windows 7 May 25, 2013 3:51:58 AM Hi I believe you will need to backup all data during install go to advanced and format C: destroying all data on C: before changing from 32 bit to 64 bit Windows It is not a simple upgrade like going from Vista to 7 (both 32 bit) Unless you have more than 3 GB of RAM (or want to add extra RAM) or are going from Home to Pro or Ultimate is the upgrade worth it. Legacy drivers for old equipment such as printers / scanners/ multifunction devices are harder to find for 64bit Windows 7 but Vista 32 bit drivers often work with 32bit Windows 7 regards Mike Barnes Can't find your answer ?
