Fix Siege Launch Issue

Job ID: 40117177

Budget: $10 – $30 USD

Rainbow Six Siege refuses to start on my Windows machine—nothing happens after I hit Play and no error ever appears. I have tried the usual quick checks (rebooting, verifying files on Ubisoft Connect, updating GPU drivers) with no luck.

I need a clear, methodical diagnosis and a working fix. Please zero-in on Windows-specific causes at game launch, such as missing redistributables, service conflicts, or anti-cheat problems, and walk me through each change you make so I can reproduce it later if needed.

Deliverable: either the game opens to the main menu on my PC or I have a concise, step-by-step guide that gets me there.
I have a great pc, but WHEN I TRY TO UNINSTALL IT SAYS, "some files cant be deleted" and doesnt let me.
