Running Multiple versions of Office on the same computer

[clivebuckwheat]

Hi

I am running Office 2003 and Office 2010 on the same. Does anyone know the reghack so that office doesn't always have to re-initialize.

For example if I use 2003 and then shut it down and then want to use 2010, 2010 must re-initialize and vice versa.

Not sure about '03 & '10 but for '03 and '07 you added the following reg entries for '07, possibly modify for '10 may work.

from CMD prompt:

reg add HKCU\Software\Microsoft\Office\11.0\Word\Options /v NoReReg /t REG_DWORD /d 1

reg add HKCU\Software\Microsoft\Office\11.0\Access\Options /v NoReReg /t REG_DWORD /d 1
