Uninstalling and then installing iTunes again will hopefully get this DLL file back and you’ll be able to boot your Windows normally.

2. Copy SyncServer.dll from another computer

  1. On another computer, go to Start, type the following paths in the search tab and press Enter:
    • C:\Windows\System32
    • C:\Windows\SysWOW64
    • The first is for 32-bit systems and the second is for 64-bit systems.
  2. A folder will pop up on the search menu.
  3. Double-click on the folder to open it, and you will see a lot of DLL files.
  4. Drag the SyncServer.dll file into an external memory device.
  5. Copy the same DLL file onto the same location in the second computer.
  6. Press the Windows key + R to start Run.
  7. Type regsvr32 SyncServer.dll and hit Enter to start the command (This action will register the DLL on the computer).
  8. Close the open windows and folders and reboot your computer.

This is a little bit unusual solution, but it could work in case reinstalling iTunes didn’t.

If you have another computer, you can transfer SyncServer.dll from it to your current machine, or you can do the same thing with your friend’s computer.

Whatever you do, don’t download the SyncServer.dll from a random website. The file could be harmful to your PC and if that happens, you will need a strong malware removing solution.
