Fix: Rainbow Six Siege crashing

Tom Clancy’s Rainbow Six is a media franchise about a fictional international counter-terrorist unit. It contains a series of missions and objectives and is seen as one of the emerging games in the modern day world.

Despite it being updated frequently by the developers, players have reported that the game opens and instantly closes. This crashing behavior is very common amongst players. This game is also associated with BattlEye. If you are also having this error, nothing to worry about. We have researched extensively and come up with various workarounds available to solve this unusual behavior by the application. Take a look.

Solution 1: Deleting R6 sound data and validating

This workaround by were endorsed by moderators of Rainbow Six Siege and mentioned that this will most likely solve the problem instantly without any further delay. Make sure that you have an administrator account available and a stable internet connection before moving on with this solution.

  1. Locate where the R6 sound data is located on your PC. Usually, it is a location like the ones shown below but it can vary based on the destination folder you selected for your installation. Here are two examples; one for UPlay and one for Steam.
C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\games\Tom Clancy's Rainbow Six Siege\sounddata\pc
Steam\steamapps\common\Tom Clancy's Rainbow Six Siege\sounddata\pc

  1. Right-click on the folder and select Delete. Either this or just delete the contents of the folder.

Most of the games available in Steam are very huge files consisting of several GB’s. It is possible that during the download/update, some of the data may have been corrupted. Steam has a feature within the client itself where you can verify the integrity of game files quite easily.

We can also try repairing Steam Library files. Steam Library is the place where all your games are present and you can only access them through it. It is possible that your Steam library isn’t in the correct configuration. There may also be a case where you have installed Steam on one drive and your games are on another one. In that case, you have to repair both the libraries before launching your game again.

You can check our detailed guide on how to verify the integrity of games and repair your Steam library. You can also do the same steps if you are using UPlay instead of Steam.

Solution 2: Updating Graphics Drivers

If you have corrupt or outdated drivers, it may be the reason why your game fails to launch or crashes midway without any prompts. Now there are two ways through which you can update the drivers: either manually or automatically. In manually, you have to personally download the driver after searching for it at the manufacturer’s website.

Before updating drivers, we will check if installing the default drivers solve the problem for us.

  1. Boot into Safe mode. Type “devmgmt.msc” in the dialogue box and press Enter. Here navigate to Display Adapters, right-click on your adapter and select Uninstall Device.

  1. Boot your computer into normal mode, press Windows + R, type “devmgmt.msc” in the dialogue box and press Enter. Most probably the default drivers will be installed. If not, right-click on any empty space and select “Scan for hardware changes”. Now check if the game works without any problems. If it does without any problems, good for you. If it doesn’t, carry on.
  2. Now there are two options. Either you can search online for the latest driver available for your hardware from the manufacturer’s website such as NVIDIA etc. (and install manually) or you can let Windows install the latest version itself (search for updates automatically).
  3. We will take a look at installing manually. Right-click on your hardware and select “Update driver”. Select the first option “Search automatically for updated driver software”. Choose the second option if you are updating manually and select “Browse for driver” and navigate to the location where you downloaded.

  1. Restart your computer after installing the drivers, launch the game and check if you can successfully play Rainbow Siege Six.

Solution 3: Disabling Cloud-save and in-game overlay (UPlay)

The Cloud Save functionality synchronizes your game data belonging to your account on the Cloud so if your data gets wiped out or you are using a new PC for gaming, your account data will be saved already on the cloud and you will just have to enter your credentials. Despite this being a useful function, there have been several reports that this causes the error message under discussion. We can try to disable it and see if the problem still persists.

  1. Start UPlay and enter your credentials. Now click the ‘menu’ icon and select Settings.
  2. In the General tab, uncheck the option “Enable Cloud Save Synchronization for supported games”. Also, uncheck the option “Enable in-game overlay for supported game”.

  1. Save changes and exit. Now launch UPlay again and try launching the game.

Solution 4: Selective Startup

It is a known fact that there are several startup programs which hinder the processes of many games and causes certain errors to take place. The best way to solve this problem is to disable those programs.

  1. Press Windows + R, type “msconfig” in the dialogue box and press Enter.
  2. Once in the settings, select “selective startup” and uncheck the option “Load startup items”. Press OK to save changes and exit.

  1. Navigate to the Services tab present at the top of the screen. Check the line which says “Hide all Microsoft services”. Once you click this, all Microsoft related services will be invisible leaving behind all the third-party services.
  2. Now click the “Disable all” button present at the near bottom at the left side of the window. All the third-party services will now be disabled.
  3. Click Apply to save changes and exit.

  1. Now navigate to the Startup tab and click the option of “Open Task Manager”. You will be redirected to the task manager where all the applications/services which run when your computer starts will be listed.
  2. Select each service one by one and click “Disable” at the bottom right side of the window.
  3. Now restart your computer and check if the error condition still persists. If the error message goes away and you are able to play your game without any problems, it means that there was either a service or an application which was causing the problem. Enable a chunk of these and check again. If the problem comes again when you enable a chunk, you would know who the culprit is.

In addition to these solutions, you can also try:

  • Rolling back your graphics driver to a previous version.
  • Checking internet connectivity and make sure you have a stable connection.
  • Disabling all antivirus software and all kinds of firewalls.
