Get multiple error codes - telling I have too little space (which was true, but have cleaned up and still not working) - and telling I don't meet the requirements. Your suggested program ran a check first that told I did meet the requirements, so this is also just bullsh*t.
And yes. I am sure I have 23h2. 100%. The suggested solutions on any pages does not work. I resign.
I think I figured out the reason for your 24H2 installation failure with the Windows 11 Installation Assistant:
Your computer did not pass the WindowsPCHealthCheck for some reason (?), which you need to pass FIRST!

But ... then there is another option, which I used on my SECOND laptop (Lenovo) successfully!
I updated Oct 18 on my old and "incompatible" Lenovo💻the big 24H2 update without any problems - it took 1 h 28 min to install the update!
It is introduced by replacing the entire operating system with a newer version and is the biggest Windows 11 update since 2021.🤔
My Lenovo has been purchased already in 2016.
I downloaded the installation file**: Win11_24H2_Finnish_x64.iso (5.29 Gb)** from the official Windows 11 download page:
Download Windows 11 (microsoft.com) (3rd installation option)
So … I downloaded the "virtual disk" or *.iso file (press the downloaded *.iso file with the right mouse button and then select "open in application" and then select "Resource management" and then click SETUP) and install from it - **everything succeeded perfectly!**😁👍
TO BE CONTINUED ...:🤔
My Lenovo's (Ideapad 310-15IKB) new Windows 11 version (24H2) got 2 more updates right away after installation --> Windows Update (SCREENSHOT).
I then tested a lot of functions and applications for a few hours (e.g. Microsoft 365 Office (paid), F-Secure Antivirus (paid), New Outlook, Firefox, Edge, Chrome, Lenovo apps, etc.)
**Everything worked fast and stable = normally!**👍
