It has been reported that for some users, when starting STAAD.Pro an assembly that should be started, ‘Bentley.SXP.Core’, fails the strong name validation. This prevents use of the Physical Model workflow.

It has been found that there are 3 dlls included in the installation that do not meet the Windows Strong Name convention. If the Windows operating system has been configured to test for the Strong Name convention, then this will prevent the dlls from loading. Typically, a default Windows installation is not set to check for Strong Name convention.

If this is a problem with your installation, please download the attached zip file and extract the included dlls. The zip file includes three dlls which should replace the ones installed by STAAD.Pro in the sub folders of your installation (typically C:\Program Files\Bentley\Engineering\STAAD.Pro CONNECT Edition):-

• Bentley.SXP.Core.dll replace existing files in:
  • …\STAAD\SPPM\Program
  • …\STAAD\RamConnection 
• Bentley.Str.Dep.MathExtensions.dll replace existing files in:
  • … \STAAD\SPPM\Program
  • … \STAAD\RCDesigner
  • … \STAAD\SProStaad
  • …\STAAD\RamConnection

• Bentley.Str.Dep.UnitConversions.dll replace existing files in:
  • …\STAAD\SPPM\Program
  • …\STAAD\SProStaad

Note that there are no changes in the content of these files, only the requirements for strong names has been addressed.
