Hello.
From a long time I tried to upgrade my Windows 11 Build 22.000.co_release.210604-1628 to Windows 11 Insider Preview 22543.1000 (rs_prerelease),but everytime I get the error "Installation error - 0x800700c1" and it won't complete. I'm not so experienced. Do you want to explain how can I fix this error ? thanks.

manually download iso then extract with WinRAR. run setup.exe.

@moin1407 where have you store those files extracted with WinRAR, which folder?
Seem I am missing that repair folder, as it constantly brings only the option to install all new and losing all data.
