Problem adding Createisocam add on

When I try adding the add on to 2.8, it shows this error

I tried restarting Blender several times and also deleted an d downloaded again the addon, but nothing seemed to improve, only the error type apparently (but I can’t add it anyway no matter the error)

df

is this in latest build ?
did not find it in an earlier version of 2.8 !

happy bl
