MPOAI9.dll error

mpoai9.dll error on opening office products

My fix may NOT be for everyone. BE CAREFUL as this deals with the registry. My scenario:

I had installed mappoint with add-in also. I then uninstalled mappoint and starting getting the dreaded mpoai9.dll error on office products. No fix found so I did this: CAUTION

I ran regedt32 and searched against MY COMPUTER for "mpoai9". My paticular machine found 10 instances of it. In each case I exported the registry key BEFORE deleting so I could recover if side effects crop up. I then deleted each key where this dll is referenced. One being a GUID key and the rest being for outlook, visio, excel, ect..... This completely removed my error on office products. Below are the keys I removed, but NOT to be used as an exact guide as to what to look for. If your not used to using the registry I caution you strongly about doing so. This worked for me, but may cause ill side effects for you.

Keys remvoed in MY system were:
