error occured during installation of assembly Microsoft.TeamFounda

[Manu]

Hi,

i created a addin for onenote which can be used to browse the work items in
TFS.
I followed the guide for creating onenote addin by Daniel.
when i'm installing the adding, during the setup i'm getting the error
"An error occured during the installation of the assembly
Microsoft.TeamFoundation.... the signature or catalog could not be verified
or is not valid"

could any one tell what to do to rectify this error.

Thanks in advance.
