Installation Error: #1603


Error 1603 is a general Windows error that means the Sync installer failed to run.

Next steps:

Ensure you are running the Sync installer as an Admin User in Windows:

  • Right-click the Sync installer and select Run as Administrator.

Still not working? Contact us if the issue persists, even after running as an Administrator.

Additional information:

1603 errors during installation are typically a result of a Windows System Policy preventing the Sync installer from running. You will need Administrator privileges to install Sync, and you may need to make changes to any Windows system policy that Prohibits User Installs.
