How do I repair a DLL file?

There are a large number of third-party tools available, and the majority of them live up to their claims of being able to repair or replace DLLs that have been damaged or lost.

However, if you decide not to use a third-party software, the SFC scanner is an utility that is built into Windows and is used to fix a variety of issues that are system-related.

Since this scanner can also be used to identify vital missing DLL files on your computer, that is what you should attempt first in order to tackle the problem of missing or damaged DLL files.

If running the SFC scanner does not resolve the issue, running DISM should do so. We recommend that you check out our post on how to fix DLL files missing from your Windows 10/11 PC for more detailed steps.
