How to Fix CDP.dll File is Missing Error in Windows?

The cdp.dll error in Windows can occur during the installation process of a program or game as well as during runtime when an application requires access to this DLL file. The error may occur if the cdp.dll file is missing, corrupt, or incompatible with the application trying to use it.

This error can halt the installation and launch of affected apps or games and compromise the proper functioning of the program while it is running. Therefore, it is vital to ensure that the cdp.dll file is intact and compatible with the application at every stage, from installation through to execution.

Fortunately, the error is relatively straightforward to fix. Below, we have outlined potential solutions that have worked for many users.

1. Run SFC & DISM Command

Corrupted or damaged Windows system files can cause this error; thus, repairing the corrupted Windows system files is recommended. It is advised to run Windows’ built-in SFC (System File Checker) command to detect and automatically repair corrupted files.

1. Open the Start Menu, type Command Prompt in the search bar, right-click on the result, and select Run as administrator.
2. Enter the following command in the Command Prompt to start the SFC scan:

   sfc /scannow

   

3. Wait until the scan completes.
4. Next, type the following commands one by one, pressing Enter after each:

   dism /online /cleanup-image /restorehealth

Allow the process to complete, then restart your computer to determine if the error has been resolved.

2. Install Pending Windows Updates

Installing pending Windows updates can resolve the error by providing the latest fixes, security improvements, and software patches from Microsoft. These updates may include newer or corrected versions of DLL files needed for applications to run smoothly, thus potentially fixing the cdp.dll error if it was caused by an outdated or buggy system file.

1. Press the Windows + I keys together to open Settings.
2. Choose the Windows Update option from the left-hand menu.
3. Click on Check for Updates, and Windows will search for and download any available updates.
   

Restart your PC after the updates are installed to see if the error has been fixed.

3. Reinstall the Problematic Program

Reinstalling the problematic program can resolve the error by replacing any corrupted or missing files related with the application, including the cdp.dll file itself. This process removes any damaged components from the previous installation and then reinstalls a latest version, which can help eliminate the error message you are encountering.

1. Press Windows + R to open the run dialog box, type appwiz.cpl, and hit Enter.

   

2. Locate the problematic program in the list.
3. After selecting the program, click on Uninstall.

   

4. Completely reinstall the program and check if the issue has been resolved.

4. Perform a System Restore

Performing a System Restore rolls back your computer to a previous state when it was functioning correctly. This process can reverse recent changes to system files, programs, and registry settings that may have introduced the cdp.dll error. By restoring your system to a point before the error occurred, you may eliminate the problem without affecting personal files like documents and photos.

1. Press Windows + R to invoke the Run dialog box.
2. Enter the following command:

   rstrui

   and press Enter to access the System Restore interface.
