The system cannot find the file specified. C:\WINDOWS\system32\<LANG_NAME>\mstsc.exe.MUI

Hello. Yes it is a incorrect path. You most likely have set incorrect paths in: System Enviroment : Regestry aka regedit.exe. I would reccomend checking your cmd.exe shortcut and fix all shortcuts to point to the correct file. You can see C:\Windows\System32 is correct C:\WINDOWS\system32 is incorrect.

Hello!

This does not seem to be the problem since I've also checked the path on a functioning system and the path is the same with all caps "WINDOWS". I've tested everything now and I just have to reset the computer and give up.

Thank you for your answers. :)

What was the end result here? I've been seeing a trend of Windows systems with missing or broken mstsc lately.

I hope this helps others as I have used it a few times this AM with Positive results.

after running another disk clean up, I restarted, ran SFC again did another restart, went to the microsoft store and installed the English language pack from Microsoft restarted again, located the remote desktop app and opened (not using any saved links) selected the server and the user was able to remote in.

Hello!

As the title states;
When I try to open Remote Desktop Connection it states this error message. I've read all other threads about this - that's why I am making my own, since the old threads about this is only in regards to 10+ year old machines.

This is a recently updated Windows 11 machine that is fully up-to-date with Windows 11, which means I cannot update it any further as the older threads states.

User log problem.

Grabbing the language pack from the Microsoft Store solved my issue as well. I had performed by the DISM /online /restorehealth and sfc /scannow without positive results before getting the language pack.
