Python Drag-and-drop broken

Question

I recently installed pywin (I had to change a registry entry to do it, but I changed it back). I also uninstalled Python 2.7, and since then, I can no longer drag and drop files onto my python scripts. I also lost my file associations. I have since uninstalled, reinstalled, run CCleaner on my registry, I've tried setting the default program to C:\\Python3\\Python.exe, C:\\Python\\Pythonw.exe, C:\\Windows\\py.exe, C:\\Windows\\pyw.exe, I've restarted my computer, but dragging files onto my script still doesn't work. I've gone through a ton of StackOverflow questions, most of them are from almost 10 years ago and don't seem to be relevant anymore. Does anyone have any ideas? Thanks.

I also tried this but it didn't help

Answer 1

I poked around in the registry and fixed it by doing the following things (not sure which were necessary and which weren't)

First, go to HKEY_CLASSES_ROOT.py and make sure the value is set to Python.File

Then go to HKEY_CLASSES_ROOT\\Python.File\\Shell\\Open and create a key called "Command" with

"C:\Windows\py.exe" "%1" %* 

as its value. I did the same to CLASSES_ROOT\\Applications\\py.exe\\open\\command

Then go to CLASSES_ROOT\\Python.File\\ShellEx and create a key called "DropHandler" with

{86C86720-42A0-1069-A2E8-08002B30309D}

as its value. that value is the CLSID of a DLL that gets the filename of the file you're dragging and runs it in command, I think?
