My new computer came with Windows 7 Home Premium installed. I have an expensive slide scanner and an early Photoshop Elements program that won't work in a 64-bit environment. Drivers are not available. Everything worked with Windows XP.
- Does upgrading with a key from an OEM version of Home Premium to Windows 7 Professional yield the same build as a clean install from a purchased disc, e.g. does it have the option of using the 32-bit and/or 64-bit mode?
- If limited to one version is it possible to switch to the other later?
- Is the 32-bit mode virtual Windows XP?
