If you accidentally deleted SyncServer.dll from your computer you’ll probably get RegSvr32 error every time you turn on your computer. Restoring this dll file will solve your problem, and we’ll show you how to do that.
Before anything, we recommend using a 3rd party software.

Solution 1: Reinstall iTunes

Since SyncServer.dll comes with iTunes software, the simplest solution for this problem is to reinstall iTunes. Uninstalling and then installing iTunes again will hopefully get this dll file back and you’ll be able to boot your Windows normally. To reinstall iTunes just follow these steps:

  1. Press Windows key and X at the same time and click Control Panel
  2. Click on Programs and Features
  3. Select iTunes and click Uninstall
  4. Restart the computer
  5. Download the latest iTunes setup file for Windows 8.1 from Apples’s website and install it on your computer
  6. Let the iTunes install and then check the functionality

Run a third-party DLL fixer

There are plenty of third-party programs out there that promise to fix or replace missing or broken DLLs, and most of them stay true to their word. However, if you are to choose just one, then there’s no way you can go wrong with Restoro.

How to use Restoro to fix missing or broken DLLs

  1. Download here Restoro and install it on your Windows 10 PC
  2. Let Restoro perform a full system scan
  3. When the scan is finished, press Clean Now
    • This is when you will have to activate your license key
    • Before the repair process starts, Restoro will create a restore point of your system in case things go wrong
  4. Restoro will now proceed to fix your DLL-related issue.

Note: While Restoro can be downloaded for free, it has limited functionality until you activate it. That being the case, if you want the full benefit of a great PC repair and optimization tool, you should purchase the full license.

Solution 2: Copy SyncServer.dll from another 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. Here’s what you need to do:

  1. On another computer, go to Start, Search and type C:WindowsSystem32 (or type C:WindowsSysWOW64 if you’re using a 64-bit system) , which is the folder that stores the DLLs. A folder System32 will pop up on the search menu
  2. Double-click on the folder to open it, and you will see a lot of dll files
  3. Drag the SyncServer.dll file into an external memory device
  4. Copy the same DLL file onto the same location in the second computer
  5. After that, go to Start, and select Run. A search box will pop up and you should type regsvr32 SyncServer.dll and hit Enter to start the command. This action will register the DLL on the computer
  6. Close the open windows and folders and reboot your computer
