Tech alert for two issues: error launching SOLIDWORKS and missing add-ins
We are currently investigating multiple reports of two problems – at this stage we don’t know if they are related, but it is a possibility since they have both started occurring at the same time. The situation is still under investigation but we are posting here to ensure you are informed. We will update this when we hear more on these issues.
Issue one: Users unable to start SOLIDWORKS, error message: “Could not load SOLIDWORKS DLL: GdtAnalysisSupport.dll” Reports are just coming in of this, so we are still in an investigation phase.
Issue two: Many missing SOLIDWORKS add-ins after installing or updating SOLIDWORKS. We believe this is a problem caused by Microsoft update KB 3072630(https://technet.microsoft.com/en-us/library/security/MS15-074) which was released on 15 July 2015 and makes changes to the Windows Installer. The following steps have been used to fix machines which ALREADY show the problem:
A) Open Installed Updates by clicking the Start button , clicking Control Panel, clicking Programs, and then, under Programs and Features, clicking View installed updates.
B) Select update KB3072630, and then click Uninstall. If you’re prompted for an administrator password or confirmation, type the password or provide confirmation.
Important note: We have seen that if KB3072630 is uninstalled before attempting to uninstall SOLIDWORKS, the SOLIDWORKS uninstall will fail. If you have already done this please use this tool to remove SOLIDWORKS: https://support.microsoft.com/en-us/mats/program_install_and_uninstall
We will provide further updates as soon as there is news on either of these issues.
