Arduino is not showing in the proteus desing suite 8

Hi All,

I have arduino library that i placed in the LIBRARY folder of the proteus of my laptop and I found it working smoothly,

But when i am placing the same .lib file into the same folder of proteus of my desktop it is not showing arduino boards when searched in proteus.

The OS and everything and specs of laptop and desktop is same.

I think that there is some auxiliary software i am missing in my desktop.

Help me to detect the arduino boards in proteus design suite 8.
