My Codesys 3.5 worked fine for a few months. Now it does not work and when trying to start it shows the message:
"Failed to istantiate the frame window. The option file 'C:\ProgramData\CODESYS\CODESYSProjectDefaults.opt' could not be loaded. (Reason: Root element is missing'.) The application will be terminated."
I have unistalled Codesys and erased the folder ‘C:\Program Files (x86)\3S CODESYS’ several times but when reinstalling the software I get always the same error.
I use Windows 7 and I have in the same computer simultaneously Codesys 2.3 and Codesys 3.5.
Any help?

Hi,
just delete the file 'C:\ProgramData\CODESYS\CODESYSProjectDefaults.opt'.
It will be recreated automatically.
