Instability in SOLIDWORKS due to conflict with Microsoft KB3072630

Alex Taguchi

SOLIDWORKS is currently investigating an issue caused by Microsoft security update KB 3072630. The following information is posted on the SOLIDWORKS website.

Summary

There is a conflict with Microsoft KB3072630 (published July 14 2015) which can cause SOLIDWORKS to become unstable when installed or updated after KB3072630 is applied. The Microsoft update makes changes to Windows Installer which prevents SOLIDWORKS installations (new, modify/repair, update, or uninstall) from being executed correctly. We are working diligently to produce a software fix as soon as possible in SOLIDWORKS 2015 and 2016, however in the interim please review the information below to prevent and correct instability caused by this conflict.

Affected software

SOLIDWORKS 2011 - 2015, and SOLIDWORKS 2016 beta.

Operating systems

All windows operating systems are affected. Per Microsoft tech bulletin MS15-074.

Symptoms

Instability may appear in many different functional areas of the software, so the list below may not be complete. Known symptoms are:

  • Missing add-ins from the SOLIDWORKS add-ins list in the Tools menu.

  • Error when launching SOLIDWORKS or opening a file: "Could not load SOLIDWORKS DLL: GdtAnalysisSupport.dll".

  • Crashes when recording, playing, or editing a SOLIDWORKS Macro.

  • Instability when using Equations.

  • Error when launching SOLIDWORKS or SOLIDWORKS Explorer: "DWG document manager library is invalid or missing".

  • Error "Could not load SOLIDWORKS DLL: sldshellutils” error returned when selecting “Pack and Go...” from SOLIDWORKS or SOLIDWORKS Explorer

Solution

First, check if you have KB3072630 installed:

  1. From the Windows Control Panel, click Windows Update.

  2. In the left pane, click View update history.

  3. Browse the list of installed updates to check if KB3072630 was installed. If present, it will have been installed on or after July 14 2015.

  4. If KB3072630 is installed on your system please review the recommendations in the applicable scenario below.

 

Important: We do not recommend uninstalling KB3072630 since it is an important security update. Please see below for the next steps. 

Important: Serious problems may occur if you make incorrect changes to the registry. We advise you to make a backup of your registry using the information here. We advise you to work with your IT administrators when following the procedures below.

Scenario 1

Users who have not yet installed or updated SOLIDWORKS since KB3072630 was applied. To prevent problems we recommend temporarily disabling KB3072630 before installing or updating SOLIDWORKS:

  1. Temporarily disable the KB3072630 security fix (we do not recommend uninstalling it) by either following steps (a)-(f) below or double-click KB3072630_Disable.reg from this zip file.
        a. Click Start, click Run, type "Regedit" in the Open box, and then click OK.
        b. Locate and click the following subkey in the registry:
        HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer
        Note If this subkey does not exist, create it.
        c. In the Edit menu, point to New, and then click DWORD Value.
        d. For the DWORD name, type "RemappedElevatedProxiesPolicy", and then press Enter.
        e. Right-click RemappedElevatedProxiesPolicy, and then click Modify.
        f. In the Value data box, type 1, and then click OK.

  2. Install, update, or uninstall SOLIDWORKS in the normal way.

  3. After SOLIDWORKS installs or updates successfully, reset the RemappedElevatedProxiesPolicy DWORD value to 0 to re-enable the security fix for KB 3072630.

 

Scenario 2

Users who have installed or updated SOLIDWORKS after KB3072630 was applied – where SOLIDWORKS was installed using the ‘standalone’ installation method. Your SOLIDWORKS installation is likely to be unstable and subsequent uninstallation will likely fail. We recommend the following method to repair your SOLIDWORKS installation:

  1. Follow step 1 from Scenario 1.

  2. Run a Repair of your SOLIDWORKS Installation from Programs and Features in the Windows Control Panel. Find the SOLIDWORKS installation then select Change, then choose Repair from the Installation Manager options and follow on-screen prompts.

  3. After the SOLIDWORKS installation is repaired, reset the RemappedElevatedProxiesPolicy DWORD value to 0 to re-enable the security fix for KB 3072630.

 

Scenario 3

Users who have installed or updated SOLIDWORKS after KB3072630 was applied – where SOLIDWORKS was installed using an Administrative Image. Your SOLIDWORKS installation is likely to be unstable. It is necessary to uninstall SOLIDWORKS, we recommend following this procedure:

  1. Uninstall SOLIDWORKS from Programs and Features in the Windows Control Panel. Find the SOLIDWORKS installation then select Uninstall.

  2. Follow step 1 from Scenario 1.

  3. Install SOLIDWORKS from your Administrative Image.

  4. After SOLIDWORKS installs successfully, reset the RemappedElevatedProxiesPolicy DWORD value to 0 to re-enable the security fix for KB 3072630.

    If you have an installation of the Microsoft® Update KB3139923 and you DO NOT have an installation of Microsoft Update KB3072630, the Windows Installer may fail. KB3139923 is part of the Microsoft Updates push in April, 2016.

    You will likely receive the following error: "Error 1719 states: Windows Installer service could not be accessed. Contact your support personnel to verify that it is properly registered and enabled."

    For more information about this issue, follow the link to a Microsoft Support forum posting by users who are experiencing the same issue.

    Good Afternoon Mike, I haven't had a chance to implement your recommendation. I will evaluate it first thing tomorrow morning.
