The possible reason can think of is e.g. lost connection with a network drive where the rtd file is saved or where cfg or cfgusr folder is located. It can also be caused by the rtd file being marked as read only.

Hi Artur,
Robot was running on my notebook at home and I am sure with no network drive. At the moment the program works correctly so I cannot reproduce the error. If in the future the problem appears again I will check your suggestion.
Thanks
Do you remember what was the operation that was being performed when this message appeared?
The autoarch.err message appears quite consistently if I have two instances of RSA running and trying to save a project in the second instance. The save appears to be successfull though, so have not really worried about it.
I have the same problem, but it happends when I try to open any file, even with a new project from robot templates or through open project... any ideas?
The only way it works is double cliking an existing file.
Try to rename your CfgUsr folder
"c:\Users\user_login\AppData\Roaming\Autodesk\Autodesk Robot Structural Analysis 2016\CfgUsr"
