I can't install .NET Framework 3.5 on my Windows 11 laptop.

Yes, I followed these steps again since the same issue occurred but it didn’t help.

The CBS logs should have helped identify the problematic component.

I tried to run driver verifier. However, now I can’t even turn on my laptop because my laptop keeps restarting and I’m getting blue screen all the time and I’m really worried.

You can disable Driver Verifier via Windows RE.

To access Windows RE, try this:

• Turn off the computer.
• Turn on the computer, but while it is booting, turn off the power.
• Turn on the computer, but while it is booting, turn off the power.
• Turn on the computer, but while it is booting, turn off the power.
• Turn on the computer and wait.

After three failed reboot attempts, Windows goes into recovery mode 

In WinRE, open Command Prompt and follow Step 3 ("Disable Driver Verifier via Command Prompt") in this article to disable Driver Verifier.

(or)

If you're willing to do a Reset (with the Keep files option), you can do so from WinRE.

Hi,

I would like to express my gratitude for your patience and help over the past few weeks in trying to resolve the problem. I successfully downloaded the .NET framework 3.5 after running the Driver Verifier.

Thank you so much!

Hi Alex607,

I'm glad it's sorted now. And thanks for the update.

Regards,
