Answer 1

Hi,

that error message is not caused by Windows or SCOM itself – it comes from an Adobe background component.

The path in the message

...\node-vulcanjs\build\Release\VulcanMessageLib.node

C:\bld\workspace\CCX-Process\release...\vulcanadapter.cc

belongs to Adobe Creative Cloud Experience / CCXProcess, which includes a Node.js module called node-vulcanjs / VulcanMessageLib.node. When that module hits an internal assertion, you see the “Microsoft Visual C++ Runtime Library – Assertion failed! … Expression: vulcan_” dialog.

So you fix it by repairing or removing the Adobe component, not by changing Visual C++ itself.

Steps to resolve

1. Confirm the source process
   • Open Task Manager → Details.
   • Look for a process like CCXProcess.exe or Adobe Creative Cloud Experience.
     • Right-click → Open file location – you should see a path under C:\Program Files\Adobe\Adobe Creative Cloud Experience\js\node_modules...
2. If you use Adobe Creative Cloud

• Go to Settings → Apps → Installed apps (or Apps & Features).
  • Uninstall: Adobe Creative Cloud Adobe Creative Cloud Experience (if listed separately).
    • Reboot the machine.
    • Download the latest Creative Cloud installer from Adobe’s website and reinstall it.
    • After reinstalling, the assertion popup should stop. This is also the recommended fix in other cases with the same error.
  3.If you don’t need Adobe CC at all
• You can simply uninstall all Adobe Creative Cloud components as above, or
• At minimum, disable them from starting:

           Open Task Manager → Startup apps.
  
            Disable Adobe Creative Cloud, Adobe CCXProcess / Adobe Creative Cloud Experience.
  

4.(Optional) Visual C++ redistributables

• The root cause is in the Adobe module, but if you want to be thorough, you can also install the latest supported Visual C++ redistributables from Microsoft; just note that this alone usually does not fix the problem if the Adobe component is still broken.

After removing or reinstalling the Adobe Creative Cloud components, the VulcanMessageLib.node assertion should no longer appear.

CCXProcess is the only Adobe app appearing.
