Error to access Calculations Library

Jul 8 at 12:58 PM
I install the Add-In on my PC (Window7). All is OK during the installation.
The Add-In is visible On Excel 2010. But when I check "Add to Pivot Table" for adding a formula, I have a msg like library calculation not found.
"There was an unexexpected error creating calculation :
There was a pb saving thus calculation to the library at :
Echec de l'initialisation du systeme de configuration"

Thank you,
Best regards,

Does that folder exist? Does that file exist? Any reason your user (or the user you are running Excel under if you are doing runas) wouldn't have permissions to create a folder or file?

You might also look at this old issue with someone experiencing the same issue. I couldn't reproduce, but if you have any suggestions to help me reproduce, let me know.
