Windows 10: PC Health Checker Fails to Install

I am trying to install PC Health Checker to see if my computer is windows 11 compatible, but every time I try to install it, it claims I need a "Windows 10, version 1803 or later" version to install it.Best of my ability, my OS build is 19044.1706. Is the 1706 the incorrect version? My windows update checker in settings says I am up to date.

:)

 

Cannot download Health Checker

When i try to download health checker I get this message


What do i do to get it

 

Device Performance & Health feature

This can be an issue with the old driver, update or hardware. However, for us to fully identify what is causing the issue, we may need to perform some troubleshooting steps. Please follow the steps below and check if it helps:

Step 1: Use System File Checker to check for system file corruption.

• Right-click (or press and hold) the Start 
  button, then select Command Prompt (Admin).
  
• Enter sfc/scannow(note the space between "sfc" and "/").

Step 2: Perform a clean boot. It will start Windows by using a minimal set of drivers
and start up programs. It will also eliminate software conflicts that could occur when you install a program, or an update, or when you run a program in Windows.

Once done, check if your Device Performance & Health will work and generate a report.

Let us know the result of the suggested steps.

Thank you.

Thanks
I am trying Eagle 51's suggestions now. Windows Update troubleshooter found a bunch of errors and fixed all but one.The update is trying to download KB4025339 again. I'll see what happens. At step one troubleshooter finishes with one error unresolved "Potential Windows Update Database Error Detected-Not Fixed". Windows update stalled at 0%.

At step 2 same troubleshooter error. The KB finished a new download failed to install.
Did step 3 KB has downloaded but fails to install.

If Eagle's suggestion doesn't work I'll try EdTittel's suggestion

Tried bothe Eagle & Ed 's suggestions - do not work. Anyone else?

I have noticed that the latest update for my nvidia drivers has failed to update. Wondering about that!
