Problem with the installation of PI in Excel

Hello,

I have a problem with the add-in PI in Excel.

I installed Historian DataLink v.4.20.01 on a user computer with an administrator count. But on the user count, there is not Historian in Excel.

I saw that the software need to be installed with the user count (with administrator rights) so i deleted the soft and installed it an other way.

PI does not appear in excel. 

I deleted Historian / Office 2010 / the keys in the regedit and the problem persists.

Anybody can help me?

Thanks.

Vincent
