Office 2007 and Office 2010 installed side by side

I was able to find a solution posted on the following blog: http://uksbsguy.com/blogs/doverton/archive/2007/07/21/how-to-get-rid-of-the-installer-configuration-dialog-when-running-office-2007-and-office-2003-on-the-same-system-for-vista-and-other-versions-of-windows.aspx
The solution was to add a registry key as specified below for both Office 12.0 (Office 2007) and Office 14 (Office 2010). I only had to do this with one application (Word) to stop the configuration wizard from appearing each time I opened any office application.

reg add HKCU\Software\Microsoft\Office\12.0\Word\Options /v NoReReg /t REG_DWORD /d 1
reg add HKCU\Software\Microsoft\Office\14.0\Word\Options /v NoReReg /t REG_DWORD /d 1

Thank you for all of your help.

My recommendation would be to use virtual machines to isolate the two versions of Office. If you have Windows 7 Pro or higher you can install XP Mode and put one of the versions of office in the VM. Otherwise VirtualBox is a great VM host.

Uninstall the versions you don't want. IMHO, Office 2010 is just enough. by default, office files will be opened with 2007.
