Several of the recent Microsoft  Security Updates for April have introduced a problem with executing VBA scripts in Bentley Structural Modeler XM & V8i, Bentley Structural Modeler XM & V8i and AECOsim Building Designer V8i. The issue may also be prevalent in other Bentley applications that use VBA scripts. The Microsoft  Security Updates may affect  Bentley applications on both Window XP and 7 clients.

Error messages include but are not limited to:
• VBA interface error: unable to run macro - invalid procedure name (error when placing Structural joist girder / bar joist / analysis Import/export)
