Mr. Dower, I apologize for not being more specific... since this is Windows based and not console driven, the file used for execution should be pythonw.exe according to the instructions at https://github.com/gurnec/decrypt_bitcoinj_seed so I right clicked on decrypt_bitcoinj_seed.pyw and went to properties and changed it's association to pythonw.exe so it would run in a non-console manner.  After doing this however, it still didn't work with the error "No pyvenv.cfg file".  Would I still follow your instructions, choosing Python instead of pythonw.exe?  Do you happen to know why the pyvenv.cfg never got created in the first place?  After all, when I do a search it's no where to be found on my C: drive.
