How to fix Cdp.dll error in Windows?

Issue: Hi, I was wondering if you could help me with an issue I'm having. I keep getting a pop-up that says, “C:\Windows|Sysyem32\cpd.dll is either not designed to run on Windows or it contains an error” and it is rather frustrating. Could you give any tips on removing this? Thanks.

Solved Answer

Windows is a complex operating system with thousands of different components working together to make it function correctly. There are processes running in the background, scheduled tasks, drivers,[1] services, and more that all have to work together seamlessly at any given moment.

One of the most prevalent file types on the system is the DLL[2] file. DLL files are similar to executables in that they implement code or call up certain elements when required. However, DLLs cannot be executed directly and often rely on hosts for their operation.

If such a file is missing or damaged, the related application, process, or other components may no longer work properly. This can result in several issues, including crashes and errors, one of which is a Cdp.dll error that can come up under different circumstances. The most common message users receive when dealing with it reads as follows:

C:\Windows|Sysyem32\cpd.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0xc000012f

The message also often references an error 0xc000012f, which can be associated with a myriad of other DLL errors. Cdp.dll is a system file, so if following the message's advice, users would have to reinstall Windows in order to fix it. This might be one of the options, but there are plenty of other methods to try before resorting to a full system reinstall.
