When I try to open STAAD Foundation Advanced from STAAD.Pro, I get the message "Could not Open STAAD Foundation Adv application".
Steps to Resolve
Reinstall STAAD Foundation Advanced; if you think this was installed before, it must have been removed/uninstalled or the folder has been renamed.
Software Download Instructions
If the program is reinstalled and still you receive this message, then you need to update the following keys in the registry.
4. Go to HKEY_CLASSES_ROOT\STAAD Foundation Adv\8.0 ; in the right hand side double-click the 'SELECTString' and update it from 18.104.22.168 to 22.214.171.124.
P.S. You must have administrative rights to edit the Registry Editor.
You must be familiar with the Registry basics to make any changes.
