Good day,
Do you know if you have seen this message when you are trying to run "for example static optimization of external load and motion from file" were selected. Is there way to resolve this issue. Please help. Thank you

Object: could not open file IO. It may not exist, or you do not have permission to read it

Hello,

If the file in question exists indeed and you can open it (for example to edit/inspect external loads) then it's possible the issue has to do with the use of absolute paths to locate the external loads file and/or data file(s) contained within them. Try to get all the files in one folder and use relative path (or no path) in the GUI, and if that works we can revisit to locate the bug/issue. Historically these issues have been hard to reproduce as they depend on directory layout that is hard to reproduce on different machines.

Hope this helps,
