+[copyparty.exe](https://github.com/9001/copyparty/releases/latest/download/copyparty.exe) can be convenient on old machines where installing python is problematic, however is **not recommended** and should be considered a last resort -- if possible, please use **[copyparty-sfx.py](https://github.com/9001/copyparty/releases/latest/download/copyparty-sfx.py)** instead
+
+the exe is compatible with 32bit windows7, which means it uses an ancient copy of python (3.7.9) which cannot be upgraded and will definitely become a security hazard at some point
+
+meanwhile [copyparty-sfx.py](https://github.com/9001/copyparty/releases/latest/download/copyparty-sfx.py) instead relies on your system python which gives better performance and will stay safe as long as you keep your python install up-to-date

 example for running straight from source (instead of using an sfx):
-  PYTHONPATH=$PWD ./prisonparty.sh /var/lib/copyparty-jail 1000 1000 /mnt/nas/music -- python3 -um copyparty -v /mnt/nas/music::rwmd"
+  PYTHONPATH=$PWD ./prisonparty.sh /var/lib/copyparty-jail 1000 1000 /mnt/nas/music -- python3 -um copyparty -v /mnt/nas/music::rwmd
 
 note that if you have python modules installed as --user (such as bpm/key detectors),
   you should add /home/foo/.local as a VOLDIR
