We Have Restored This Installation to an Older Version of League of Legends

What Leads to the League of Legends Error “We Have Restored This Installation to An Older Version”?

We discovered the following root causes:

  • Date and Time Settings: Occasionally, this error may be brought on by incorrectly configured date and time settings on the computer. The servers use the date and time configurations to determine the time zone and to validate the certificates, both of which are necessary to establish a secure connection. This makes the date and time configurations crucial.
  • Server Update Error: Additionally, it was discovered that, occasionally, changing the date and time to one day earlier than the actual time solved the problem. There appears to be no explanation for this workaround, which can only be characterised as a launcher problem.
  • game data: Another possibility is that this error is being caused by certain game files being corrupted or missing altogether. To enable the launcher to patch the game to the most recent version, all game files must be in their proper locations. Otherwise, it might stop the game from starting.

  4. Return to the game and look to see if a patch is available.
  5. Return to the “Time & Language” settings and click the “Set Time Automatically” toggle to deactivate it if the patch loop persists.
  6. Select “Change” from the menu that appears just below “Set Time Manually.”
  7. Next, set the clock exactly “24 hours” (or more) behind the actual time and date.
  8. Verify whether the problem is still present.
  9. You can reset the time in the settings if the patch loop has been fixed.
