Whether I use Windows Update or the Application Assistant, I get this same error. Error message: There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x800703ee) Antivirus and external drives disabled Chkdsk returns no errors There's plenty of space on C drive as well as in the EFI partititon C drive has been cleaned up All drivers have been updated All Windows 11 requirements have been met I'm not sure what else to try.

Hi thesoulpuppie, Glad it's sorted. Thank you for the feedback. Regards,

Thank you! After the last changes, Windows 11 downloaded from Windows Update cleanly and on its own without any issues. When I restarted my PC, the upgrade began and once it completed and returned to desktop, my Windows 11 Pro 64-bit was in place just as I wanted. This is now working perfectly and I am so happy! Thank you very much for your awesome analysis and patience!

After updating the BIOS and device drivers, run the Windows 11 setup. 0x800703ee should no longer occur. But if another error, such as 0xC1900101, occurs, Avast and Comodo must be uninstalled.
