But, when I go to insert clipart from my other Office apps, they run into a problem due to Visio. It goes through the same Microsoft Office Visio 2003 install wizard, and after failing, it will open the clipart that WAS installed for 2007.
Enter one of the following using Run.... Substitute Excel, Visio, or PowerPoint for Word as necessary:
Office 2007: reg add HKCU\Software\Microsoft\Office\12.0\Word\Options /v NoReReg /t REG_DWORD /d 1
Office 2003: reg add HKCU\Software\Microsoft\Office\11.0\Word\Options /v NoReReg /t REG_DWORD /d 1
To change an install path, you need to be running the application with Administrator privileges. Unfortunately, I wasn't able to right-click on the Shortcut and select "Run as administrator," I needed to find the source file. Right-clicking and opening the Properties dialog to get to the source didn't work either, as it was unavailable. I browsed to C:\Program Files\Microsoft Office\Office12, right-clicked on POWERPNT.EXE and clicked "Run as administrator." From here, I tried to insert clipart again, and this time I was able to provide a path to my Visio disk and the problem has been resolved.
I'm not sure what to suggest to others that do not have a Visio 2003 disk -- someone had one (or a network install) to get it on your machine originally. Likely your IT department that originally set up your computer will be able to solve this -- assuming they're accessible.
