After installing Windows Update KB3097877 on Windows 7 machines, SOLIDWORKS can fail to launch. Microsoft has identified the problem with Windows Update KB3097877 and a newer version has been re-released to resolve this issue.  

Windows Update KB3097877

If you have installed Window Update KB3097877 and SOLIDWORKS is now crashing during launch, then follow these steps to resolve it:

  1. Uninstall the original Windows Update KB3097877.
  2. Download the newer version of the update from the Microsoft download site.
  3. Install the new version of the Update.

This Windows Update also has been known to cause issues with Outlook,  network logons and Windows 7 sidebar gadgets.

The re-leased patch has the same name as the affected one, which will make correcting the issue more difficult for some admins. Other options to remove the malfunctioning patch are to roll back to an earlier Restore Point (KB3097877 was released November 10th) or to uninstall the patch at the command prompt. See detailed instructions from Microsoft here.

This patch was part of security bulletin MS15-115, a critical update designed to prevent remote code execution triggered by malicious fonts.
