Wrong Executable digital signature for Add-on

Hi All,

I am trying to install an Add-On a Citrix Server.On the Server installation is done and Add-on is connecting but when i log into Citrix as a client and try to connect the Add-On at that time i am getting an error message "Wrong Executable digital signature for Add-On " and after that status represents failed.

What would be correct solutins?

Is this is a problem of Add-On or there would be any setting at Citrix Server?

Please help me as soon as possible.
