[Calista]

Ich habe Win 11 24H2 installiert..... leider wurde das Setup von Win 11 abgebrochen .. wegen unkompatiebel .. !

Wer kann helfen ?

Check if you are in this situation:

to check the CPU you can use CPU-Z which must be started from administrator account:

You could bypass W11's hardware requirements by installing it with Rufus.

Rufus won't bypass the new requirement for SSE4.2 support.

24H2 got released in the release preview channel for windows insiders in late May
https://blogs.windows.com/windows-insider/2024/05/22/releasing-windows-11-version-24h2-to-the-release-preview-channel/

also, OP has yet to tell us what kind of CPU/processor that person is using.
SSE4.2 support was first added on the Nehalem series (1st gen Intel core) of Intel CPUs and also started with the AMD Bulldozer & Piledriver series of AMD CPUs (the FX series).
any old Intel & AMD processors before these series do not have SSE4.2

Has it been confirmed they actually want full SSE4.2? I did check my old AMD has working POPCNT instruction, this is the one setup wizard explicitly asks for. I wonder if bypassing those blocks would still allow to install and boot in this case, so no SSE4.2, but this instruction alone is still supported on some older CPUs.

You actually have to check for POPCNT support by looking at specific bit in ECX register's value after executing CPUID instruction with EAX register set to 0x1, it's not really part of any SSE set. SSE4.2 check could be used as shortcut and future-proofing though...

AMD supports POPCNT and SSE4a at same time, but someone tried installing 24H2 with Athron II X4 605 and failed.

 

NVIDIA has same limitation beginning with driver branch R555.

If you have a CPU new enough to Contain that SSE4.2 instruction set (CPU's made on or after 2012) then installing 24H2 should work, without fail.

I DO have a cpu new enough to run 24H2, and I AM, and I love it. 

Best OS I've run since DOS 6.22.

windows 11 iot enterprise  does not have all these restrictions and etc. and bloatware free. you can install "windows 11 iot enterprise"

NVIDIA finally fixed the compatibility issue with processors without SSE 4.2 by updating MSVC to 17.8.8.

NVIDIA graphics driver version 555.85 through 565.90 are affected by the issue. Anyway, it's a good news for Core2 or Phenom2 users.
