Whenever I try to open any files I get the error messages "StaadFoundation MFC Application has stopped working" / "Attempted an unsupported operation".
Right click on STAAD.foundation Advanced icon (short-cut) and select the option "Run as administrator". Open a file and see if the issue is resolved.
If not, install the patch to upgrade to the latest version 06.02.00.59 (see the attached image). Follow the software downloads instructions as mentioned in the following link.
In the 'Filter by' section select, Download category as "All" (scroll down).
After downloading the file, you will right click on it and select "Run as administrator".
Once done,right-click on STAAD.foundation Advanced icon (short-cut) and select the option "Run as administrator" to make sure all the settings are done correctly.
