Hi all,
Very similar situation here while I see that no real solution was provided.
I have installed AvogadroOrca4.1.exe to create chemical structures and generate Orca’s input files. Once I created the .input file I cannot open it again with Avogadro and I get the error:
Reading molecular file failed, file PATH.format.
I tried saving as other input files (.com,.xyz) and the exact same error is showing up. The only format I can open is .cml. I also try with the latest Avogadro and I get the same issue.
Is there anybody who resolved this issue? I have seen somewhere people talking about openbabel could be missing, any clue if that is the reason? and if yes how can I solved it (installing openbabel did not work)
I am using Windows 10 x64.
