Tips to Repair a Ksuser.dll Error
When you receive a ksuser.dll error message, check whether the DLL file is present on your computer or not. If you find the DLL file is missing, download the ksuser.dll from a reliable free DLL download website or copy the file from another Windows PC with a similar configuration as yours. After obtaining the file, save it in the C:\Windows\System\32 folder, which is the default location for the file.
If the error is not caused due to a missing DLL, check the version of DirectX you are using. If you are using an older version of DirectX, install the latest version on your PC. To know which version of DirectX you are using, perform the following steps:
- Go to Start and click Run.
- In the Open box, type dxdiag to open DirectX Diagnostic Tool window.
- Here, you can find the DirectX version information under the System tab.
If you have an older version of DirectX installed on your computer, download and install the latest version. You can obtain the latest DirectX version from the DirectX download website or Windows Update website.
In case you are receiving the ksuser.dll error when you run a particular application, uninstall the application and reinstall it again to fix the error. If the error still persists, look for an update for this program. If you find the update, download and install it to fix the error.
If the above steps fail to repair the DLL error, we recommend you run a virus/malware scan of your entire system, using an advanced antivirus tool, such as STOPzilla Antivirus and an anispyware tool, such as Spyware Cease. If scan results show ksuser.dll as infected, delete or quarantine the file using your protective tool and install a new copy of this DLL on your system. Also, to ensure that your PC is safe against the latest threats, make sure that these protective tools are updated on a regular basis.
Finally, schedule regular registry scans to ensure that entries related to your DLL files remain true.
