FYI, this error shows up every time the program launches (screenshot attached-using Windows 10).
126.96.36.199 was the first release after we finalized the Beta. However, we didn't get this error fixed until 188.8.131.52 which is available on the website or within the automatic updater when you open StruCalc.
So 184.108.40.206 is supposed to be 'Final' but I still see the error mentioned above every time I open the program. Just letting you know.
