How to Fix Rainbow Six Siege Crashes, UPlay, Steam, Won’t Start, Errors, Invitations, Sound, Lag

#1 Fix UPlay and Steam install conflict

Majority of R6 gamers are getting this issue — here’s the sure-fire way to fix it:

  1. Quit Steam.
  2. Go to C:Program Files (x86)SteamSteamAppsCommon and rename the folder “Tom Clancy’s Rainbow Six Siege” to “Tom Clancy’s Rainbow Six Siege bak”. (That is, add “bak” to the end of the folder name.)
  3. Launch Steam. In your library, right-click on Siege and click “Delete Local Content”
  4. Change the name of the folder back to the original name, “Tom Clancy’s Rainbow Six Siege”.
  5. When you press “Install” in your library, it will find the existing installation instead of downloading the files all over again.
  6. You can now launch the game.

#2 Invite Friends / My Invitation Fix

  • Exit UPlay and start Rainbow Six on Steam, then invitations will work.
  • Another option is for the lobby leader to go to options tab -> game -> and switches team settings to “open for friends”. Then everyone joins him through uplay client (not overlay).

#3 Fix for Invalid CD-Key Issue

Go to the Rainbow Six folder in steam (Steam->Steamapps->Common->RainbowSix) and set the Rainbow Six Siege.exe to Run as Admin.

#4 RainbowSix.exe File corruption detected! The program will now terminate.

Simply validate your game cache in Steam to fix this issue.

#5 No Sound Fix

Try switching your default audio device between speakers and headphones, and see what works.

#6 Rainbow Six Siege randomly crashes mid game

Firstly, make sure you have the specs to run the game, then run this free driver update tool to make sure all the required software are up to date.

#7 Poor FPS Fix for AMD Users

Turning off XFire has proven to work for most AMD users.

#8 Rainbow Six won’t start, Missing DLLs

If Rainbow Six won’t start due to missing DLLs, you can simply Google the missing DLL files and place them in your Rainbow Six install folder. Or better yet, use this free DLL fixer tool to instantly find the needed files.

    Rainbow six siege still doesnt work for me i tried everything and the game just cannot lauch

    • Michael Haner

      Same here. I get the splash box, then the screen goes black then back to desktop.


      I found a way to solve ut you have to update your graphic card pilotes


      You can download them and install them for free of the internet
      (E.g: if you have radeon graphic card type on google radeo graphic card pilot download click on the first link put un the specs of your pc and download and install it if it doesnt work just message this post again )


      Radeon* graphic card

  • Hampus Hegre Brauten

    Had Siege installed on two PCs on the same network and got Error [2-0x00000047]. Solved it by rebooting the router.

    Don’t know if this is the optimal solution, but it worked in my case.
