[2020] Stuck on Splash Screen Uplay Installer

Hey, Shaky6P2!

Welcome to the forums. I have seen similar reports from other users on the forums and they have advised the game was being blocked by Bitdefender. Here's how to fix it:

-Launch Bitdefender
-Click Settings
-Click exclusions
-Click add exclusions
-Add rainbowsix.exe

If you have Bitdefender please try the above steps. If you do not have Bitdefender or the issue persists please try the following:

Run the game with ADMINISTRATOR RIGHTS.

Verify your game files.
It is possible that the installation of your game is faulty. To fix this, please verify your game files:

UPLAY
EPIC GAMES LAUNCHER
STEAM

Disable Background Applications.

Make sure your OPERATING SYSTEM is UP TO DATE.

Reinstall Uplay.

Update your GPU Drivers:

AMD
NVIDIA

Should the issues persist after completing the above steps, please GET IN TOUCH, attaching DXDIAG and MSINFO reports to your SUPPORT CASE.

Thank you.
