Hi @mahdi
Do you use Windows system ? Which one ? Maybe 64bits …
What do you see inside directory “%APPDATA%/.Tribler/”.
Did you tried to install 7.2.2 (see https://www.tribler.org/) ?
Windows 10 x64 Tribler 7.2.2 x64
There is a logs folder with 3 empty log files
Hi again
I gat somes file in “%APPDATA%/.Tribler/”, and there is a “triblerd.conf” on my computer.
I gat also the directory “%APPDATA%/.Tribler/logs/”.
To see all of this, i … choose in Windows to not hide extension of each file and see even hidden files.
See for example …
Anyway, the trick explain here is only for Tribler 7.1.1 when someone gat error starting Tribler.
What problem do you encounter @mahdi
I’ve unhidden them.
I have same error
Failed to execute script run_tribler.
I first had installed 7.1.5 (same error) then upgraded to 7.2.2 still same error
Ok @mahdi, maybe @S.Pan-TUDelft o someone else 'll find what is the problem.
i just discover debug panel with “Ctrl + d” (not really understand parameters here 
).
i gat repeated lines in “%APPDATA%/.Tribler/tribler-core-error.log”, even if Tribler work.
@mahdi do you perhaps have a different python version installed. We still use python 2.7.
@owned Thank you for your assistance.
I uninstalled python. not solved. I’m using pre-build binaries
