How to scan Documents in MS Office 2013

I'll second Graham's recommendation. I have Word 2003, 2007, 2010, and 2013 installed side by side, following Graham's instructions.

Why bother with the virtual system (which is not available in all Windows 7 versions)? You could install 2003, 2007, 2010 and 2013 on the same system, if you wished, (apart from Outlook), provided you took a little care over configuration. - http://www.gmayor.com/Toolbars_in_word_2007.htm

The other option you may want to think about since you're on a Win 7 platform would be to create a virtual machine (using XP Mode) and install a copy of Office 2007 on that machine (if you still have a copy of Office 2007 laying around along with the necessary license). I think Office 2007 was the last version that had the menu option to scan a document into Word on the Microsoft Office Tools menu. I've done this on one of my systems using a networked HP All-in-One device and it works just fine. (I did have to install the HP All-in-One on the VM as well, using the starter CD that came with the device; it included the drivers for XP and Vista.)

When I need to scan a document into Word so I can edit it, I just fire up the VM and use the Microsoft Office Document Scanning menu option under the Microsoft Office Tools menu to scan the document; I could just as easily use the Microsoft Office Document Imaging menu selection if all I want is a graphic image. Once I scan the document and send it to Word 2003 (which automatically performs the OCR so it is seen as text by Word), I save it as a .doc document and store it in the Public Documents folder on the host system. At that point, I can open it in Word 2013 on the host system and the mission is accomplished. It's not exactly an elegant solution and it took me a little time to set up the VM (and of course you need the copy of Office 2003), but it's fairly simple at that point. I don't know I would want to do it for more than a couple of workstations, but it worked for me. If it helps anyone else, that's great.
