Fix: Something Wrong When Loading the DC-WFF.DLL

You may see the loading error of the DC-WFF.DLL file if it is not properly registered in the Windows environment. Moreover, corrupt installation of conflicting applications (like TP-Link) may also cause the issue at hand.

The user faces the flashing “Something wrong when loading the dc_wff.dll” error after booting his system and on every subsequent restart of the system (mainly reported after a Window update).

Before moving on, check if temporarily disabling the antivirus of your system resolves the DLL issue (some users reported that the issue was caused by Avira antivirus). But be very careful as disabling the antivirus of your system may expose your data/system to threats.

Solution 1: Re-register the DC-WFF File

You may encounter the DC-WFF file loading error if the file is not properly registered in the Windows environment. In this context, re-registering the DC-WFF file may solve the problem.

2. Now execute the following (to unregister the file):

   regsvr32 /u dc_wff.dll

   

3. Then execute the following (to register the file):

   regsvr32 /i dc_wff.dll

4. Now exit the Command Prompt and reboot your PC.
5. Upon reboot, check if the DC-WFF DLL issue is resolved.

You can also end the task in the Task Manager and disable it in the system’s startup settings (till the issue is resolved). If the issue persists, then try if using the Autoruns and deleting the problematic entries solve the problem.

Solution 3: Reinstall the TP-Link Application and its Driver
