ProperTree, CPUFriendFriend and other pyScripts fail on my mac?

I've installed Catalina using OpenCore and trying to fix some small stuff. I noticed earlier that I was not able to use apps like ProperTree. I got no Tkinter window and the terminal said:

    window = plistwindow.PlistWindow(self, self.tk)

I didn't bother at the time since I could use another editor. But now I'm trying to use the CPUFriendsFriend.command and get similar error:
 

Traceback (most recent call last):
  File "/Volumes/[Storage]/OSX FIX/CPUFriendFriend-master/CPUFriendFriend.py", line 338, in <module>
    c = CPUFF()

    self.u = utils.Utils("CPUFriendFriend")
NameError: name 'utils' is not defined

[Process completed]

Anyone else had these problems? Is it Python/Tkinter ? 
I tried google "nameError: global name is not defined"... and directs me to different coding forums where people having problems with their scripts... But I hardly think that the coders of ProperTree, CPUFriendFriend done anything wrong... 
I would be very thankful for any help.
