Running Microsoft Office 2003 alongside Office 2007

I recently had problems when I installed Office 2007 with Office 2003.

What happened was, all Excel files kept opening with Office 07 when I wanted them to open in Office 03
For Word, a popup saying 'Installer is Configuring Office' or something similar kept coming up for both versions when started.

I have a found a fix for both these issues
Modifying the System Registry may be dangerous if not done properly. It is recommended you set a System Restore point and read the steps carefully.

Microsoft Office Excel
To get Excel 03 files to open with Excel 03 instead of 07, do the following (note, you may need the Office 2003 CD)
1. Go to Start --> Run and type excel.exe /unregserver
2. Go to Run and type "C:\Program Files\Microsoft Office\Office11\Excel.exe" /regserver

That's it!

Microsoft Office Word
To stop the useless Installation dialog boxes from coming up:
1. Go to Start --> Run and type Regedit and press Enter.
2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Word\Options
3. When you click the Options Folder, go to Edit --> New --> New DWORD Value.
4. Name it NoReReg and press Enter.
5. Right click the new Value and click Modify.
6. Type 1 and press Enter.
7. Now navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Word\Options and do the same as above.
