installation error

[Kalpesh99]

Yesterday, I upgraded my system from Windows 10 to Windows 11. After the upgrade, whenever I start my laptop, the following message pops up:
"Error: Abnormal installation. Product installed. Required entries do not exist. Cannot continue!!!"
What does this mean, and how can I resolve it?

@Kalpesh99, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

It seems like after upgrading to Windows 11, you're encountering an error related to a failed or incomplete installation of either a software or system component. The error message, "Abnormal installation. Product installed. Required entries do not exist. Cannot continue!!!" suggests that certain registry entries, files, or settings expected by some software or system process are missing or corrupted after the upgrade.

Uninstall Problematic Software

Go to Settings > Apps and uninstall any software you installed around the time of the upgrade, especially if you think it might be causing the error.

Fix System Files

Open Command Prompt (Admin) by pressing Win + X and selecting Command Prompt (Admin).

Type this command and press Enter: sfc /scannow

If it doesn't fix the issue, run this next command: DISM /Online /Cleanup-Image /RestoreHealth 

Check for Windows Updates

Go to Settings > Update & Security > Windows Update and install any updates that are available.

Update Drivers

Open Device Manager (press Win + X and select it).

Right-click and Update drivers for devices like graphics cards, network adapters, and storage.

Rollback to Windows 10 (if nothing works)

Go to Settings > Update & Security > Recovery.

Click Go back to Windows 10 if it's still available.

I hope this helps.
