How to get rid of the installer/configuration dialog when running Office 2007 and Office 2003 on the same system

After installing both Office 2007 and Office 2003 on same system you may face the problem of the following dialogs below every time you switch between Office 2007 Program and Office 2003 Program. Which is so disturbing and time killing.

Add the following Registry entries to solve the problem.


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

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

Just copy each line and paste in the RUN dialog (Win+R) and press OK.
After doing it if the dialogs appear further just continue the installing process for that time.
It will not shown again.
