DLL File Error

Question

Just got these brand new PCs in with Windows 11 Pro 24H2 and installed a CAD program, the program worked for a few days. Then started receiving a dll file error on all of those PCs (see image) saying the dll might be missing, corrupt, or wrong version when I run a certain task in a program. I checked the folder that it is located in and I see the file is there. I even replaced the file with the same one from a PC where the file isn't running into the error. Still does not fix the issue, I contacted support for the program and they said the've never seen this issue before. They tried all the fixes they can think of and came to a conclusion that it has to be something to do with windows.

Please let me know if you have any ideas of what could be causing this.

So far I've tired these fixes:

Reinstalled CAD Program Reinstalling NVIDIA DriversUpdated CAD ProgramReplaced .dll file with issueReplaced folder .dll file is inUninstalled AntivirusDisabled Windows Defender Ran sfc/scannow

Ran DISM /Online /Cleanup-Image /Restorehealth

Installing Windows Updates

Hi MCJ_842

Welcome to the Microsoft Community

Understanding your problem, you have encountered a DLL file error

Run the Microsoft Repair Tool:

Use Microsoft's “Framework Repair Tool” to fix potential framework or system issues.

Reinstall the Visual C++ Runtime Library:

Many CAD programs rely on the Visual C++ Runtime Library. Ensure that all versions of the Visual C++ runtime libraries are installed correctly and attempt to reinstall them (all versions from 2005 to 2022).

Trying to re-register the DLL files can solve problems caused by corrupt or missing DLL registration information.

To re-register all DLL files in the System32 directory, run cmd as administrator and enter the following command and run it

for %1 in (%windir%\System32*.dll) do regsvr32.exe /s %1

If the above does not work try upgrading in place

Hello Merek.Z - MSFT,

Thank you for responding, I've tried the Framework Repair tool and reinstalling Visual C++. Then I tried re registering the dll files through the command you provided. Also I tried using regsvr32 [the name of the DLL file] and I got an error (seen below).
