SOLIDWORKS/EPDM 2015 sp4 Missing Add-Ins, Crashing or "GdtAnalysisSupport.dll" Error

SolidWorks is currently investigating multiple reports of three problems , all of which share the same root cause, a conflict with Microsoft KB3072630 (https://technet.microsoft.com/en-us/library/security/MS15-074) that was pushed out on July 15th. The problem has been reported to their developers as Software Performance Report SPR 902645 and SolidWorks is working with Microsoft toward a resolution. Note that the issue could manifest itself in the following ways:

1. Add-ins missing after an upgrade of SolidWorks to a newer Service Pack (SP)
2. When launching SolidWorks or opening a file, SW returns the error “Could not load SOLIDWORKS DLL: GdtAnalysisSupport.dll”
3. SolidWorks crash when recording, playing, or editing a SOLIDWORKS® Macro

This update makes changes to the Windows Installer and can easily be found by opening a CMD window and typing wmic qfe|find “3072630”.
