PRONTERFACE reports error message "AttributeError: 'NoneType' object has no attribute 'write' "

[FredBello]

Hello,
I can't open PRONTERFACE, even using the latest version.
WINDOWS 10 64 BITS
PRONTERFACE: printrun-2.2.0_windows_x64_py3.10

The following error message appears:
"Traceback (most recent call last):
File "pronterface.py", line 62, in
File "printrun\pronterface.py", line 2596, in init
File "printrun\pronterface.py", line 171, in init

I don't know what to do, could you give me some suggestions?
Thanks

Hi @FredBello,
this looks like you have a malformed printrunconf.ini. Close Pronterface and try to rename or delete that file and then start it again.
Please check the file printrun.log too. You can add the file here in a zipped version for further investigation if needed.

You should find both files in your root user folder, like c:\Users\YOUR_USER_NAME\ where YOUR_USER_NAME is your windows user name. Please check the other possible location at c:\Users\\YOUR_USER_NAME\AppData\Local\Printrun\Printrun\ in case you can't find them on the first place.

Remark: ...\Appdata\... is a hidden folder, you may want to allow showing hidden files and folders in the file explorer.

Hello, Diving Duck
Your instructions were spot on. After deleting the files you mentioned, the program started again.
I would like to thank you very much for your attention and generosity in giving your time to help, thank you very much!

God bless you and your family!
