update not installing

Just to make sure I've got thing right,I'm running Win11 Version 26H2 OS Build 26300.9457

Had a few updates show up today,one d/l and installed fine,one won't it is 2026-10 Security Update (KB5127648) gives a error of 0x80070017

The other update that installed just if needed for info is
KB5127694

Checking through update history and this one seems to have failed a few times tried on the 15th,17th,19th and the 24th,everything else seems to be working fine,anyone else got issues with this one update?

I just wanted to add,I've tried the troubleshooter for win updates,it asked to run update diagnostics,which it then said failed to run,system seems to be running fine,apart from this one update.

0x80070017 (WIN32: 23 ERROR_CRC) -- 2147942423 (-2147024873)
Error message text: Data error (cyclic redundancy check).

Use Windows Update Troubleshooter.

• Right-click on Start button and pick Settings
• Go to System > Troubleshoot
• Click on Other Troubleshooters > Windows Update and click Run button.

Download Windows updates manually.

• Go to the official Microsoft update catalog;
• Enter a specific update code, for example, KB4481031
• Select the correct version and click Download
• Click on the link and Windows will update your computer

Resetting the Windows Update components can usually solve these types of issues.

I've manually downloaded, with no issues! the update, ran the package,it got part way through installing only to give a popup saying that update was not installed.
