Hi, can you update this script for the python 3.33. It does not run. Thanks Ian
Hey @IanD26 - yes of course, I'll take a look as soon as I can...

Hi @IanD26 - a couple of important things have changed since I last looked at this TrueCrypt script many years ago:
- I now develop using a Mac rather than Windows
- TrueCrypt is no longer actively maintained, and has been superseded by VeraCrypt
I already released a port of this script that is compatible with VeraCrypt. Are you able to use that updated version instead by any chance?

Hi again @IanD26 - if you'd prefer to try an updated version of this original script, I've just made some changes and it now appears to be compatible with Python3. Please keep in mind that I don't have access to a Windows machine with TrueCrypt, so I can't test it properly, but I think it's probably okay now!
Hi, it works perfectly. Thank you very much for this. Now I can try to find this old password.Thanks againIan
