Use Word 2003 and 2010 on the same PC

Issue

I currently have Microsoft Office 2003 and 2010. I want to install them on the same PC, is it possible?

Solution

Just add 2 registry key.

Using the registry editor:

HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Word\Options\NoReReg 

value:1

HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Word\Options\NoReReg 

value:1

...Office\11.0\... pour office 2003 
...Office\12.0\... pour office 2007 
...Office\14.0\... pour office 2010 

From a command prompt:

  • reg add HKCU\Software\Microsoft\Office\11.0\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 

Thanks to Eriic for this tip.
