Saw there was an update 4.0.2. for Gimp version 3.2.4
So I uninstalled the version I had and decided to update. Well I tried the zip file first and after unzipping, put the whole folder into my plugins. Opened gimp and put the path in folders pointing to it.
Restarted gimp and no show.
So I deleted all and tried the installer, no show so made sure it was pointing to the correct file 
Shut down my computer, still nothing after restarting.
Deleted all again and tried the zip again, making sure it was for windows and gimp version 3.2. Nothing 
Edit:-
Just tried the installer again - Still nothing
Never had this problem before
