Resolve Simple Scan Error Opening a Kofax Scanner Manager: Class not registered 0x80040154

Use this article to resolve an error after upgrading or re-installing an older version of Synergize Simple scan specifically v1.3.x. to v1.4.x. The application fails to properly unregister 2 kofax control files (kmgp3032.ocx and kscn3032.ocx). The control files have been taken out on v1.4. When the application is launched and system registered DLLs are loaded, the application errors out thinking that the control files are missing. Users get the following error in Synergize Simple Scan:
