What causes error 80040154, “Class Not Registered”?
If this error occurs during startup, the likely reason is Microsoft Visio is not installed on the system or the system does not meet minimum version requirements for Visio. ProMax supports Visio 2002/2003/2007 Professional or Standard. See the ProMax release notes for further information and requirements concerning service packs and hotfixes. Ensure that Visio will run without error outside of ProMax before attempting to start ProMax. If this error occurs during execution of a ProMax solver or specifier, is is likely that your computer is missing the Microsoft Windows script control or other scripting components. Normally, these components are bundled with the operating system for Windows 2000 and Windows XP. However, some software will remove these components when the software is removed from the computer. For these systems the scripting control will require manual reinstallation. Please contact BR&E if you need assistance with this error.
