Reading molecular file failed - Cannot open any file


I have installed AvogadroOrca4.1.exe to visualize the ORCA output files.
However, I cannot open any file with this software.

Once I tried to open any file (.xyz, .inp, or .out), an error message popped up; Reading molecular file failed, file PATH.format.
I also tried other versions including 1.1.0, 1.2.0, and 1.91.0. But all showed the same error message and failed to open any files.

Is there anybody who resolved this issue? Am I missing any step to activate Avogadro?
I am using Windows 10 x64.
Please let me know how to properly set up Avogadro.

Thank you.


I’m having the same issue.
I can open old orca .out files (Orca and a couple of new ones (Orca 4.1.1). The only meaning full difference I see between the files I can and the ones I can’t open are the vibrational freq. calculations. The .out files with freq. calculations do not open.
I’m providing a link with two examples, the one I can open (without-freq.out) and the one I can’t (with-freq.out).

Finally, I would like to thank the Avogadro team for their work!
