I certainly did not modify any of the files. GIMP plugins seem to be primarily EXEs, but some of them come with DLLs too. Could you just link the download for me so I can give the documentation a once over? Have you installed those other dependencies yet.
ill link you, but I have not installed those yet cause I cant figure out how.

On the page there is a "gimp-normalmap-win32-1.2.1.zip" this one ahs an exe in it, should I use this one instead?
