To install Windows 10 on your PC, the processor (CPU) must support the following features: Physical Address Extension (PAE), NX, and SSE2. Most CPUs have support for these features, so if you receive this error, it is likely because the NX feature is not enabled on your system.

If your computer does support these extensions, you could still try using ISO media. In some instances, you might have to switch from your current architecture,  64 to 32 bit since these requirements mostly affect installation of 64 bit Windows 10:

See instructions: How to download official Windows 10 ISO files

This likely means your computers processor (CPU or brains of your computer) lacks an important instruction called CMPXCHG16B.

In order to install a 64 bit version of Windows 10, this instruction must be present.

• Updating your computer BIOS and Chipset drivers can sometimes resolve this issue.
• Your CPU is probably too old and is not supported.
• Your best option in this case is to downgrade to a 32 bit version of Windows 10 instead, even if you are presently running a 64 bit version of Windows. If you prefer having a 64 bit version based on factors such as the amount of installed RAM, chore associated with having to reinstall applications and hardware drivers, then its best you stick with the current version of Windows installed.

Try the following:

- Disable Hyper-Threading in your BIOS

- Disable Virtualization  in your BIOS

- Check if there are any BIOS updates for your computer

Note: Some older video cards might be incompatible with Windows. It likely means the graphics adapter has or is approaching End of Life status which limits the level of support the manufacturer can provide. The card will likely function just fine for general purposes, just don't expect it to work well for scenarios such as playing games. There might even be glitches with certain casual games not working well at all.

If the Get Windows 10 app still prevents installation after uninstalling the card, try using the ISO media to upgrade:

If you installed a new video card without uninstalling the old video card, you might have reinstall the old card, then uninstall it properly through device manager.

Check the manufacturers website to find out the status of the video card. Check if there are at least Windows 8.1 drivers available. If there are no drivers available or manufacturer support options, you should purchase a new video card.

Click Apply and OK to confirm changes. Your computer will be restarted to apply the changes.

After restart, log in and launch Disk Management – press Windows key + R > type: diskmgmt.msc then hit Enter on your keyboard.
