Hmm.. maybe someone here can help me too. I tried using the Voldrix onlyfans-dl. I edited the onlyfans-dl.py with editor because idle didn't open. Now I found the idle.bat inside my python installation, which opens the .py file and I am able to edit it, but I am not able to download with the .bat. Everytime I run in cmd onlyfans-dl.py username it wants me to choose a program to open. With the .bat it just opens the .py file to edit and with the idle.exe nothing happens and the cmd jumps back to entering a command.
Edit:
If I install Python standard (not all Users) it is put into Roaming from where my IDLE doesn't work with my 64bit, even though I installed the correct python application.
If I install Python for all Users IDLE won't start. Just closes the window and the cmd jumps back to command entering.
