Hi,
if you would like to help me I will really appreciate it!
In need a hand because I'm still getting problems, when I start AC with my App activated, console says that there are some problems with the moule 'App/python/Assetto-dash.py'. I think it's a problem with the directory structure of the modules but I'm not sure about that. Have you any suggestion?
Did you use pySerial or another module?

@pipplalTA Hello! I believe it is using pySerial. Maybe you need to install that as a prerequisite? I'm getting this up and running again for my new sim setup so I'll be installing this again. So I'll let you know what I find...

I think I need some help. I can not add the acsys library to python, it gives an error how can i not do it.

Hi, do you know where do i get the AC module? (pip command maybe?)

@demirkolerme & @andersonvnicius & @pippalTA It looks like you might need to enable Python in Assetto Corsa in
"Documents\Assetto Corsa\cfg\gameplay.ini"
Look for this line and change it to 1
[PYTHON]
ENABLE_PYTHON=1
