1, open the control Panel → programs and features → turn on or turn off Windows features → media features to see if Windows Media Player is in front of the hook, if you want to see the 2nd step, if not, please tick and wait for the system to be installed and restart the system manually. Look at step 2nd again.
2, Win7 Run the command prompt as an administrator, and then enter the following instructions, or directly download the batch process in the attachment to run as an administrator (XP system runs directly): For%i in (*.dll) do regsvr32/s%i
The Win7 system must be run as Administrator or the command will not execute properly. If there is a "register Server error" error window, close the error window directly, continue to run the command, know that the last automatic stop, or batch processing prompts registration success. Finally, manually restart the computer again!
