Dual install of Microsoft Office 2003 and Office 2007

You thought it would be easy. You thought Microsoft would have all the kinks out of the system since having to deal with "multiple-version" install issues since the first version of Office. But alas, you are wrong, and so was I!

PROBLEM #1:
After installing Office 2007 I noticed that my Access and Word 2003 now come up with a install dialog. Well after a little research I found the fix to stop the install window from popping up again.

SOLUTION #1:
Just go to the run box (or hit the windows key+r) the type

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


PROBLEM #2:
I now get the error:

"Run-time error '430' Class does not support Automation or does not support expected interface."

when I try to run Access 2003 code which worked perfectly before!

SOLUTION #2:
Create a shortcut to run each msaccess.exe as an administrator. This allows each version to register itself on start-up.

To set up this workaround:

1. Delete any shortcuts created by installing Office. (These lack the Run As Administrator option.)
2. Create shortcuts to msaccess.exe from each version of Office. (Right-drag them from the folder in Computer.)
3. Right-click the shortcut, and choose Properties. Click the Advanced button. Check the Run as Administrator box.

Each time you start Access, you will need to click the Continue button in the User Account Control warning dialog.

For Access 2007, you can use a normal shortcut, i.e. Run As Administrator is not needed for this version.

PROBLEM #3:
After uninstall of Excel 2007 I get the error message of

One of your object libraries (stdole32.tlb) is missing or damaged. Please run Setup to install it.

SOLUTION #3:
Ran the Repair option of the MS Office 2003 Setup.



If you think this fixes all of your problem then think again. According to Information about using 2007 Office suites and programs on a computer that is running another version of Office
there are other problems you may deal with. For example only the latest Outlook version can be used.
