Hi,
I reinstalled Windows 11 from scratch but now, even after all possible attempts, MKVToolNix and MKVExtractGUI do not work with any .mkv file.
MKVToolNix gives this error: “the file Fahrenheit 451.mkv was not recognized as a supported format (exit code 2)”.
MKVExtractGUI from this in the log:
“[2025-03-19][09:44:36] “C:\Program Files\MKVToolNix\mkvmerge.exe” --ui-language en --identify --identification-format json “G:.…mkv”

Does anyone know what I can do? Thank you
P.S. Fahrenheit 451 is HEVC and AAC LC mkv file
“open file error” is the generic error message when the program cannot even open the file for reading, never mind determining its content. It can be due to lack of permissions, wrong path, inaccessible network locations etc.
