I have Office 2007 and Office 2010 installed side-by-side. How do I stop the setup / configuration window from appearing each time I open a different version? If I open 2007, it will go through the configuration process, then I can use 2007 without issue until I open a 2010 application. Then, when I open any 2010 Office application it will go through the configuration process.
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.
