Why does not installing a new Firefox version work in this case?

En

My mother's laptop does not work as it should. When trying to use the Firefox installer a new version of Firefox.

When trying the following message comes:

Why does not installing a new Firefox version work in this case

If I then click on diagnostics, I get these 2 great messages:

Why does not installing a new Firefox version work in this case - 1

I do not seem to have any installation rights. And calling the Task Manager is also denied me:

Why does not installing a new Firefox version work in this case - 2

I ask for help. Will only help reinstall Windows or can I get my rights back? In my opinion, there's not much to save.

In any case, a big thank you to all the answers and the great community 👍

Info: Windows version 8.1 (new updates do not work anymore when trying to install them)

Kind regards

Edit: I also Can't ACCESS MY DRIVE C: \

The PC denies me that

Sounds like the account has no admin rights.

To Firefox installation:
You probably tried to start the installation before the program was completely downloaded. Please wait so long and try the installation again.

If I doubt it, the UAC would have opened.

For me it looks as if you are not logged in as administrator in Windows, but z. B. As a guest with limited rights.

Ask your mother for the right password.

But maybe it helps also a driven laptop restart (in the shutdown menu: Restart)

Qu

Okay, not if it's generally disabled.

I myself "Always notify" enabled.

Restart does not help and I can't open programs with admin rights, because then again a network error that could not be accessed…

En

No. That's not it, because I can't start anything with admin rights or something like that. I have no rights. There are always network errors

En

May be. How can I get these back? I can't start anything with admin rights let alone install programs and any things. Task Manager does not work either.

I also can't access drive C!

Thanks for the tutorial, but the computer does not respond when I click OK on the settings. It does not let me do anything… Not even accessing my hard drive

Then I would reinstall Windows. Secure the important data first.

Which Windows is installed? - For Win8.1 you have to enter my knowledge when installing the product key. - Do yo have him?

En

Windows was preinstalled when purchased. Should I use a USB stick for reinstallation? I do not think that I can do that on Windows itself, because it is completely gone.

Ru

Is Win8.1 or Win10 installed?

En

8.1

Ru

When installing Win8.1 must m. Knowing the product key can be entered. - The problem is that you do not know him.

You should now try to install the Windows Product Key Viewer, see: https://www.chip.de/...63752.html, to read it.

If that does not work, you would have to install the Win8.1 installation with a so-called "Generic Product Key" * = 334NH-RXG76-64THK-C7CKG-D3VPT and read out after installation your product key stored in the BIOS and then for the To enter.

Whether you install from a DVD or a USB stick, the PC does not care.
This is what you fix in the BIOS, where you put the desired drive in front of the HDD at the boot order.

Many Thanks

I forgot that there's another solution:
As a rule, laptops can be reset to factory settings.
There's no need to enter a product key.
Details can be found in the laptop manual.

However, if the laptop was originally factory-installed with Win8 and not Win8.1, then the update to Win 8.1 would have to be made afterwards. - In that case, I would prefer a Win8.1 installation.

Do not know what you did before, but that sounds like a virus or trojan.

Would completely reinstall the BS. The ISO you get here with the tool
