Error executing program! (31)
"No application is associated with the specified file for this operation."
Since I was trying to view a picture with Infranview, I figured that I did not add the file associations in Infranview, so I checked, and they were there. I then added the associations again, this time as an Administrator, but that did not solve the problem. I then figure that it must be because Total Commander is installed in the Program Files folder and that folder is heavily protected by the Windows UAC, so I uninstalled Total Commander and re-installed it in a root folder on my drive: C:/TOTALCMD. This is where it used to be in the beginning. That did not solve it either!
I then checked using Windows Explorer and everything works as it should in there! I can open any picture/file by simply double clicking on it, but not in Total Commander. In Windows 7, 8 and 10, I never had this issue, just in Windows 11. This problem is not just limited to pictures, but also to videos, but it works if I try to open Word files!

Anybody has any ideas?
