When you have Command Prompt open type the following command into Command Prompt and press Enter.

Try Registering the dll file.

To begin go open Command Prompt as Administrator then type the following command. Replacing "path & filename of dll file” with the exact details of the missing .dll file.

regsvr32 "path & filename of dll file”

Copy and paste the file from another Windows 11 PC.

If you have access to another Windows 11 device (that you trust) you can try copying and pasting the file from that PC to your PC. Just make sure you trust the source PC.

Download the files. (Highly advised against)

Lastly, and I highly recommend against it but you can try downloading the file from an online source like https://www.dll-files.com/ This isn’t the safest option going which is why I suggest against it but if you’re super desperate and don’t have time to reinstall Windows this might work for you. Again, this isn’t a recommended option but it may help you get out of a tight spot if you are willing to risk it.
