I just installed upgraded my Office install from Office 2007 to the 64-bit (x64)version Office 2010. I had to completely remove my Office 2007 applications including SharePoint Designer 2007, because no Office 2007 applications can coexist with any 64-bit Office 2010 application.

“That’s OK,” I thought; “who wants the old stuff when I can have the shiny new stuff?”

I fired up SharePoint Designer 2010, eager to do some edits to our SharePoint 2007. That’s when I was greeted with this lovely error:

“Microsoft SharePoint Designer cannot be used to edit web sites on servers prior to Microsoft SharePoint Server 2010.  To edit these sites, you need to use SharePoint Designer 2007.”

I can’t use SharePoint Designer 2010 with my SharePoint 2007 site nor with my customers’ SharePoint 2007 sites? Really? I hope that whoever at Microsoft made the decision that SharePoint Designer 2010 would not support SharePoint 2007 sites was able to find another job after he/she was unceremoniously fired! Could you imagine if Word 2010 could not open Word 2007 or Word 2003 files? Ridiculous.

Ok, so I can’t use SharePoint Designer 2010 to edit my SharePoint 2007 sites and I can’t install SharePoint Designer 2007 on my computer. What’s the answer? Virtualization. I’m spinning up a virtual machine that will host an instance of Office 2007, as well as a few other apps.
