Hi there, There isn't any key associated with your version of Siege. Instead the license is activated from Steam on to your Uplay account. Could you please try verifying your game files in Steam then restarting both Uplay & Steam and running them both as administrator?
Please also make sure you're not using game share and haven't refunded Siege on Steam.

I verified the game cache and 3 files were missing (23gb) so I guess that could be the problem XD, and also the key I was talking about was when you buy rb6 on steam it gives you a key to type in uplay to link the accounts.

Yup that used to be the case in the past and still is with some older titles. Newer games such as Siege, The Division, AC: Origins etc don't come with a key in Steam, instead the license is added to your Uplay account when you launch the game from Steam. You'll then always have to be linked to the same Uplay account you originally redeemed the game on.

problem solved, thanks for the help

No problem, thanks for letting us know it's resolved.

Hi SnowBlack92 You need to be logged into the Uplay account that you originally redeemed the game on when playing on PC, that doesn't seem to be the account you are posting from. Thank you

Hey, You need to play Siege on the original account you redeemed it on. But to clarify, progress does not transfer from console to PC, so you will need to start from level 1 again.

Hello! There is no activation key for playing on the TTS. The TTS is automatically added to your account if you have access to R6S once the TTS is live.

Hi CaganMuhammed, We can certainly pass your feedback around that on to the team.

Do you own the PC version of the game as well? A purchase of the game on one platform does not entitle you to the game on every platform, just to clarify. Your progress is non-transferrable between platforms as well, as we do not support cross-platform functionalities in Rainbow Six Siege.

Hello Fang.Zulu, if you have recently purchased Rainbow Six Siege from Steam, you will not need an activation key for Uplay PC - the game will be automatically tied to your account when you first open the game. If you are being asked for a key, it may be that you are signed into the incorrect Ubisoft Account, i.e. one where your license for Rainbow Six Siege is not tied. Please check this for me.

I've also created a Uplay account
BTW playing on MAC OS

When looking for your game in GeForce NOW, you should see a tile for the game in question with a tiny Steam icon in the bottom right corner - please try launching the game via that tile.

Hello there! We normally see this occur when a player activates the 2-step verification on the wrong account. Please check that when you go to setup the 2-step verification, you see the correct account details for the Ubisoft account your game is tied to. If you need assistance with that, please do reach out to our team. Thanks!

Hi everyone! Sorry to hear you having issues with activating and launching your game. Firstly, it's always good to empty the cache of Uplay PC if you are having any issues. For those purchased on Epic, please make sure you have your country/region on both the Epic and Ubisoft accounts as the same. If this is not the case, please reach out to us. As for Geforce Now, we are currently investigating the issue of being asked for a key when attempting to launch your game via Geforce Now. This is usually down to a regional incompatibility with the version on your account, to what is available via the Geforce service. I am sorry for any inconvenience caused.

Hi Ullityxd! Sorry to hear you being asked for a key. Have you tried empty the cache of Uplay PC? If you still have issues, can you confirm where you purchased the game? Thanks!

Hey Yo.GetClapped, thanks for reaching out and welcome to forums! If you have by accident linked your Rainbow Six: Siege copy of the game to the wrong account, we can look at possibly transferring it over to another account for you. To do this, we will need you to reach out to us via one of the following channels: 1. Support website by creating a ticket. Once done, you can advise your ticket number in this thread and we will review it.
2. Facebook
3. Twitter Please note that you will be asked to provide proof of purchase, therefore depending on the platform you've activated it on, make sure you refer to the following steps: 1. Uplay PC
2. Steam
3. Epic

Hey, Have you downloaded and launched the game from the Epic launcher?

Hello! The game should automatically activate & link to your Ubisoft account, without any need for an activation code. Is it Uplay or Epic that is requesting a key, and have you been able to launch the game at all? If the game doesn't seem to be activating, try launching both Uplay & Epic as administrator: https://support.ubi.com/faqs/000025662/ Thank you!

Hey BT-XPLAYER, Thanks you for reaching out! Apologies for any inconvenience however is there any possibility you could translate your message to English, and we will do our best to assist you. Alternatively, if you prefer to contact us in Turkish language instead, can you visit our support website and submit a support ticket, where a member of our team will get back to you accordingly!

Hey polat159, Thanks for reaching out and welcome to forums! To correct this situation, I recommend the following troubleshooting steps: Navigate to the Ubisoft Game Launcher cache folder, by default located here: C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\cache
Please note that the Uplay client must be fully shut down at this point and not running in the background.
Open the cache folder and move the "ownership" folder to a safe location.
Once you have backed up that folder, delete the "cache" folder.
After deleting the cache folder, please verify the game files within Epic:
- Open Epic
- Navigate to the game in your Library and click the cog icon.
- Click the Verify button once the drop down menu appears.
- After verification, the launch option appears again. If verification is not available within Epic, please install the game files in Uplay. If you need to verify the files after installation, you can do this via the following:- - In Uplay, click on Games tab at the top of the window
- On the next screen, hover over the game tile. This will make a little arrow appear at the bottom right of the tile
- Click on this arrow to make a drop-down menu appear, then click on Verify files When this has been completed, try launching the game again. In terms of 'Epic Games Service is Unavailable' message, I would recommend to try launching your game via Uplay PC launcher instead, and see whether that helps. Keep us updated and should you have any questions, let us know!

Hey there folks. A key shouldn't be required after purchasing and launching the game. Instead of being provided with a key the game should be applied to your Ubisoft account. If you're being prompted for a key or experiencing an authentication error it's usually because you're signed in on the wrong account. If you're not aware of any other accounts you own or if you suspect this isn't the issue in this case please reach out to our Support teams directly for further assistance. You can reach us either through the support website by opening a live chat session or alternatively through our social media accounts on Facebook and Twitter and they will be able to create a support case for you. Thanks!
