Mathematics Addin doesn't working (can not be enabled) in Word

Hi AndrejJ,

I have the same problem as you had. I also have XP (SP3) and Office 2010. My system drive is D:. I tried to use your advice, but I can´t find the registry keys. Can you help me on that??

But maybe my problem is a little different from yours:

After a lot of experimenting (i.e copying the mscoree.dll to all kinds of places) I finally had the Mathematics tab in word, but still the Add-In didn´t work (everything in the Drop-Down Menus was grey), I couldn´t click on anything. Very likely the mscoree.dll isn´t the only file out of place after the original installation.

Not only did the Ad-In not work, after closing Word, i tried to reopen it, but it got hung up on trying to load the Add-In. I had to finnish it, before it was even open. When using administrative rights, i got offered to deactivate the add-in, which I chose in order to be able to open word again.

Still I think my problem seems to have the same basis as yours, because in the Add-the-Add-In -dialogue it said the loading place is C:\windows\system32\mscoree.dll (instead of D:\...). So if you can help me with those registry keys, I will give it a try.

Best regards, R.

Hi Backsidewalkaround,

simple start regedit.exe and navigate to the key

HKEY_CLASSES_ROOT\CLSID\{188AD2DC-7454-4817-8179-0102C1F36531}\InprocServer32

On the right pane double click to "(Default)" and change "C:\WINDOWS\system32\mscoree.dll"
to "D:\WINDOWS\system32\mscoree.dll".

Repeat the same for Add-in in the OneNode if needed.

HKEY_CLASSES_ROOT\CLSID\{782ACB0C-5993-4C36-9646-AA196EDAA741}\InprocServer32

Sure, all this is only applicable for 32-bit OS and Office.

Regards,
Andrej
