How To Fix Application Error 0x0000135 on Windows 11- Step By Step Guide #2022

Be it in terms of reliability, app compatibility, or under-the-hood advancements, Windows 11 is one of the greatest incarnations of the operating system to date. Even this edition, though, is not without flaws. Many customers have reported that while trying to launch a.EXE file on their PC, they receive the 0xc0000135 error. Though the problem is unusual, it is luckily quite easy to remedy, and because it is a software-based problem, you may do so on your own. Today, this article will explain how to fix application error 0x0000135 on Windows 11.

But, before you get too far into correcting the problem, it’s important to first figure out what’s causing it and how to keep it from happening again.

What Triggers the 0xc0000135 Application Problem?

Merely described, the process is caused by lacking files from the.NET framework connected to the computer. Moreover, because every application requires a specific.NET framework to run, if a file in the framework suddenly disappears, it will affect all applications that utilize that framework.

The issue occurs when programs ask to utilize the Windows Communication Foundation (WCF) and Windows Workflow Foundation (WWF) in the.NET framework, but they have not been configured on your machine.

Take this to have a better understanding of the situation. If you have two versions of the.NET framework installed by default, frameworks 3 and 4, and a DLL file in framework 3 gets into trouble, all programs that use it will either not open or function smoothly, however, apps that use framework 4 will run perfectly.

Additionally, this issue might occur as a result of mismatched drivers or remnant cache files from a prior installation. Whichever the issue, following the procedures outlined in this article, it may be readily remedied.

Let’s get started on tackling the issue now that you’ve learned about it.

Methods for Resolving Application Error Oxc000135 on Windows 11:

Method 1: Reinstall the.NET Framework 3.5.

This version of the framework is most likely previously installed by default. However, as previously said, re-enabling the framework can simply fix the problem.

  • To reactivate the .NET framework, you need to go to the Start Menu and search for Windows Functions. In order to continue, pick the ‘Turn Windows Features On or Off’ tile from the search results.
  • In the newly displayed window, identify the ‘.NET Framework 3.5’ choice and choose it by tapping the preceding button. Then, before the checkbox, use the ‘+’ icon to enlarge the section even more.
  • To pick the choices, check each checkbox preceding the individual item shown in the enlarged column. Furthermore, to pick it, tick the checkbox next to the ‘.NET Framework 4.8 Advanced Services’ box. Next, before the checkbox, click the ‘+’ button to enlarge the section.
  • Afterward, to pick each individual choice, click on each of the checkboxes before it. After that, on the bottom right side of the window, tap the ‘OK’ option to verify your choices and activate the selected features on your machine.

The computer may prompt you to reboot your PC after the changes have been installed. After restarting, try running an app that was giving you trouble, and the problem should be addressed.

Method 2: Delete Your Device’s Cache Files:

Deleting cache files is another excellent way to get rid of any leftover files from a previous.NET framework installation. Windows now have many cache groups, not just one. As a result, you may quickly complete the procedure by following the steps listed below.

1. Start cleaning up your device’s disc by running Disk Cleanup:

Disk Cleanup is a Windows feature that lets you delete unwanted items from your computer. Despite the reality that the utility has been in the operating system for a long time, Microsoft just modified the means of accessing it in the most recent version of Windows.

  • To use the Disk Cleanup on your device, head over to the Start Menu and seek for it by typing Disk Cleanup. Then, from the search results, select the ‘Disk Cleanup’ tile to launch the program.
  • Additionally, you may use the Run program to start the Disk Cleanup program. To do so, hit the Windows+R tab key at the same time to launch the Run tool. Now, in the text box, input cleanmgr and press Enter to launch Disk Cleanup.
  • After that, on the Disk Cleanup wizard window, select the drop-down option to see a list of all disk drives. Select one of the discs you want to clean up with Disk Cleanup, then press the ‘OK’ button to let Windows calculate all the files that can be deleted.
  • A new disk defragmentation window will pop up once the processing is complete. Some file types would already be picked by default. You may now navigate down the list to see all of the files that can be cleaned up and choose a specific category by checking the box next to each one.
  • The Disk Cleanup tool will also inform you how much disc space each file group takes up on the screen. Additionally, when you pick numerous categories, you will be informed of the total amount of space that will be saved by eliminating the files.
  • To continue, choose the ‘OK’ option once you’ve chosen your desired group of files to erase.
  • After that, press the ‘Delete Files’ authority to delete all of the files in the specified categories from your system.

Method 2: Undo the KB5012643 Patch

After loading the OS Build 22000.652 KB5012643 update, there is a common problem arising in various systems. Microsoft is working to resolve the problem in upcoming updates, so you’ll have to queue for that. Meantime, the options described above should suffice. However, if they haven’t and you’re in a hurry to fix the problem, you may undo the KB5012643 update.

  • To revert to an earlier version of the operating system, you need to move to the Start Menu and access the Settings window by clicking the ‘Settings’ tile.
  • To proceed, go to the Settings window and click the ‘Windows Update’ button on the left sidebar.
  • Then, from the window’s right side, find and select the ‘Update history’ item underneath the ‘More choices’ tab.
  • Scroll down to the bottom of the ‘Windows history’ page and select the ‘Uninstall updates’ icon under the ‘Related settings’ tab.
  • Afterward, select the KB5012643 update on the next page and press the ‘Uninstall’ option to continue.  If you don’t see the KB5012643 update in your updates history but still get the 0xc0000135 application issue, you can roll it back to the most current version.


Finally, these are the ways using which you can fix the application error 0x0000135 on Windows 11.
