Fix application error 0xc0000135 in Windows 11
Source-checked About 10 minutes
Answer
Update Windows, identify the app's required.NET runtime, and install or repair that runtime from Microsoft or the app's official installer. Do not download individual DLL files.
Confirm the symptom and protect the current Windows state
Record the Windows build, affected app or device, exact message, and the last change before the symptom began. Save open work, keep installers and recovery credentials, and create a current backup or restore point when the supported recovery may change apps, drivers, partitions, or system files. Test one supported change at a time so a useful result can be attributed and reversed.
Start with the supported check
Install Windows updates and restart, then try the app again.
Apply the current setting
Check the app publisher's system requirements to determine whether it needs .NET Framework or a modern .NET Desktop Runtime.
Test the result
Install the required runtime from Microsoft, or run the official installer again and choose Repair if offered.
Escalate safely
If the error remains, repair or reinstall the app from its official source; do not use DLL-download sites.
Verify the intended result before broader recovery
Repeat the exact task described by “Fix application error 0xc0000135 in Windows 11” with a harmless test. Confirm the affected app, account, device, file or setting now matches the Answer, then recheck it after one fresh session or restart when that is part of the supported workflow. Keep the original data and recorded starting state until the result is stable; if only one component still fails, keep further recovery limited to that component.
Video walkthrough
If it does not work
- If the application still fails, preserve the full error code, app version and Event Viewer entry, then repair or reinstall only that app and its publisher-documented prerequisites. Do not download DLL files, change compatibility globally or edit the registry for an unspecified 0xc error.
