When I try running an analysis in STAAD.Pro, I get an error message "Fatal Error: Cannot start analysis Engine".

The error may be caused by the fact that the paging file size which has been set in Windows in your machine is not large enough to run the program.

1. You can determine whether this is true by doing the following. Make sure you are logged in with Administrative privileges before you attempt any of the following steps.

Using Windows Explorer, locate the file "SProStaad.exe" which should be present in the folder "\Sprov8i\staad\sprostaad".

Run that file by double clicking on it. If it comes up with a message that the paging file size is not large enough, that is an indication of the problem mentioned in step 1 above.

2. If the above is true, you can remedy the error by doing the following:

In Windows, go to Control Panel - System - Advanced Settings

Select performance options. The total paging file size for all drives will be listed in a window. You may want to increase it.

Exit those settings dialog boxes, and try running the program again. Chances are it should work this time.

If that does not resolve the issue, please uninstall STAAD.Pro and reinstall the software.
