I currently have Office 2003 on my laptop and I'd like to load Office 2010 and be able to use either version. My O.S. is Windows 7 home premium 64 Bit, 4Gb Ram, 360Gb free on hard drive and Service pack 1.

Having spent some time searching for options, I propose partitioning the hard drive using the "Shrink Volume" method and installing Office 2010 on the new drive. My concerns are:

1. Is Windows automatically on the new partition or do I have to install it?
2. Office 2003 is 32 bit, and I know I'd need the 32 bit version of Office 2010 if it was on the same drive, but can I use the 64 bit version on the new drive?
3. I can only have one version of Outlook if on the same drive. Does this still apply with a separate drive?
4. Any other comment or advice please - other than upgrading to later versions of Windows or Office.
