-    python -m pip install --upgrade pyinstaller mutagen Crypto
+    python -m pip install --upgrade pyinstaller mutagen pycryptodome
 
 Once you have all the necessary dependancies installed, just run `py pyinst.py`. The executable will be built for the same architecture (32/64 bit) as the python used to build it. It is strongly reccomended to use python3 although python2.6+ is supported.
