SOLIDWORKS: Crashes – Windows 7 Users MicrOSOFT KB3186497



In Mid-June we started to see multiple SOLIDWORKS crashes on machines with Windows 7 that updated Microsoft Security Patch KB3186497 – Offline Installer .NET 4.7, we have tested SOLIDWORKS 2015, 2016 and 2017.


SOLIDWORKS has created a SPR#1032308 as shown below:




The .NET Framework can be hosted by unmanaged components that load the common language runtime into their processes and initiate the execution of managed code, thereby creating a software environment that can exploit both managed and unmanaged features. The .NET Framework not only provides several runtime hosts, but also supports the development of third-party runtime hosts.


*This however does not affect Windows 10 machines.


There is a work around to correct this issue:


  • Go into control panel/programs and features
  • Uninstall Microsoft .NET Framework 4.7
  • Re-installed Microsoft .NET Framework 4.6.2
