There are several potential solutions that can help fix the Rainbow Six Siege synchronization failed error, including checking the integrity of the game files, allowing Uplay through the firewall, and ending the Uplay process via Task Manager.

Check the Integrity of Game

One of the first things you should try is checking the integrity of the game files. This will ensure that all the necessary files are present and in good condition, which can prevent errors from occurring. To do this, you can follow these steps:

  2. Locate Rainbow Six Siege in the list of games and click on the gear icon next to it.
  3. Select the Verify files option and wait for the process to complete.

Run as Administrator

Run the Uplay application is running as an administrator. This can ensure that the application has the necessary permissions to access and modify the files and settings required for the game to run properly.

To do this, you can follow these steps:

  1. Go to C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher or wherever you have Ubisoft installed.
  2. Right-click on the upc.exe and select Properties.
  3. Click on the Compatibility tab, then check the box for “Run this program as an administrator”.
  4. Click OK and repeat the above steps for the uplaywebcore.exe as well.

  6. Open Ubisoft Connect.

By running the Uplay application as an administrator, you can ensure that it has the necessary permissions to access and modify the files and settings required for the game to run properly.

  1. Search for Windows Security in the Search box and open it.
  2. Choose Firewall & network protection and then choose Allow an app through firewall.
  3. In the next page, locate Uplay and its related processes and make sure the Public and Private options are checked.

Delete the Files

  1. Go to C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher or wherever you have Ubisoft installed.

  3. Click on the Compatibility tab, then check the box for “Run this program as an administrator”.
  4. Click OK and the above steps for the uplaywebcore.exe as well.

It’s also important to note that sometimes, the error may be caused by a bug or an issue with the game or the Uplay client. In this case, the best thing you can do is to keep your game and Uplay client updated, and also report the bug to the developers. They will release a patch or update to fix it.
