When trying to perform a calculation, the error message 10996 "File Project.EXT not found" appears.
This error is caused by unsufficient user rights in the working directory.
Solution: Either you can open RFEM with the right-click and using the option "Run as Administrator" or assign the access rights for the working directory using Windows Explorer. You can find the path of the working directory in RFEM under "Options" -> "Program Options" -> "Data Files" -> "Working Directory".
