Logic pro and midi guitar 2 issues

I’m sure this has been covered but I’m new. I’ve downloaded everything, but logic pro shows an error that the file couldnt be opened. Ive looked at tons of how to fix videos and none work. I’m very experienced with logic pro and this is a first for me to have that message for a plug in. Ive tried everything and I’m stuck . Help!!! thanks ( I can use midi guitar 2 on my desktop..but as soon as I go to logic pro…nada

What “file”? Can you send the exact wording of the error message?
