I get a file trying to calculate a file Warning No. 1145. What is the reason for this?


The reason for this message is that you are in viewer mode. When installing RFEM or RSTAB, a viewer version is installed additionally to the normal version. It appears as an additional icon on the desktop. In this mode, you can open the results files, but you can not make any changes.

If you want to edit and calculate a file, you should open the icon without the "Viewer" addition.
