Cannot complete the install because of a conflicting dependency

Hello all,

I clicked on (Help ---> check for updates) in Gama 1.8.1, but I got the error that the operation cannot be completed. Can anyone help me resolve it, please?

Here are the exact details of the error:

Supporting info:

I also have Gama version 1.8.2 on the same computer, as sometimes I move from this version to the other. I do not know if this might be causing the problem
