Some VBA applications require certain C++ run-time libraries to work properly and when not present on the machine throw run time errors.When Microsoft Office is installed/or present on the machine then these library files are automatically present. If not then they need to be installed separately.

Please download the following run time libraries and install:

• • Microsoft Visual C++ 2008 Redistributable Package (x86)
  • Microsoft FM20.dll [using Microsoft ActiveX Control Pad]
  • Microsoft Visual Basic 6.0 Common Controls 

• Uninstall and reinstall Structural Modeler (so that the dlls are properly registered by the installer)

                                                        OR

• Manually register the dlls with the following commands:

1.  C:\Documents and Settings\Administrator>cd "C:\Program Files\Common Files\Bentley Shared\IEG\OpenSTAADBentley"
2. C:\Program Files\Common Files\Bentley Shared\IEG\OpenSTAADBentley>regsvr32 /s STAADLibBentley.dll
3. If RAM Structural System is installed on the machine then try to register the following file:C:\Program Files\Bentley\Engineering\RAM Structural System\Prog>regsvr32 /s RAMDataAccess.dll
4. If RAM Structural System is not installed on the machine then register the following dll:C:\Program Files\Bentley\Engineering\RAM 3DViewer\Prog>regsvr32 /s RAMDataAccess.dll

Also in Vista and Windows7 machines if the UAC is turned ON, the required OpenSTAAD and RAMDataAccess dlls don't get registered. In such a case "Compile Error in Hidden Module" error is thrown or the GUI is displayed but on importing/exporting a model, the application throws a "VBA Interface Error"

Therefore either set UAC to Off or manually register the dlls mentioned above.
