Gmad.exe closing after pressing any key/ dragging file

I’m trying to decompile a gma file with the gmad.exe (IT’S IN THE BIN FOLDER), but it just keeps closing after I press a key or even drag a file into it.

i swear to god if i get banned for posting in the wrong section

Solved, thanks laddy.

Try just moving the gmad exe to the addon folders and just using -file and point it towards it like it tells you.
Drag and drop may not work due to folder permissions(C:\Program Files and Program Files(x86) require administrative permissions from the OS).
