Is OCS 2.3.1 compatible with ManageMSofficeKey/MSofficeKey?

Hello,

I'm Trying to install  ManageMSofficeKey's plugin and I have got some errors in my MySQL database when I run the setup.sh script.

Error: "ERROR 1060 (42S21) at line 19: Duplicate column name 'GUID' "

Is the ManageMSofficeKey's plugin compatible with the lastest version of OCS Inventory

Thanks in advance :)
