Flight simulator will not launch with Win 11

I set TPM and Secure Boot before I did the checks.

Ok did you do the unsecured install ?

Yes it matters

If your PC doesn't meet all the requirements for Windows 11 and you installed it anyways that's why (tpm 2 and secure boot ) you would've gotten a msg that you don't meet all the requirements and some features would be disabled

Certain games require the secured windows

I'm Samy an independent advisor. Welcome to the Xbox community. How are you?

These steps can help you, give it a try.
Check for updates on Windows Update, update everything including optional/additional updates.
1. Logout from Xbox app and Microsoft Store app
2. Look for the Xbox app and Microsoft Store app in the Windows menu, right-click, click app settings and then click terminate, restore and reset.
3. Clear the store cache type ''wsreset'' in the Windows bar, run as admin, and wait for the screen to close and open the store automatically.
4. Open the Microsoft Store app, click on the 3 dots in the upper right corner>downloads updates>get updates and update everything.
5. Restart your PC, log in to both apps and see if that solves the problem.

Check if the account you purchased the game is logged into the Microsoft Store app on your Windows. In the upper right corner of the app you can check this out. Also check that your PC's region is correct.

No with older pc if you don't have tpm 2 certain functions won't work

When you do the Pc health check scan and when it's done click more info

If tpm and secure boot are flagged then it won't run some xbox games
