I Don't exactly know where this goes. I have Windows 11 23h2 LOF.

I have Windows 11 23h2 and would like integrate all the languages in my NTLIte ISO but when I do I get a error that says "Not applicable to this version." Is there a utility that can convert it ro something that is applicable to Windows 11 24h2? or how do I do this without a utility??

This question was answered on NTLite forums. W11 has 4 different versions of the Language Pack, they're specific to each release:

• Windows 11 24H2 Language and Optional Features ISO
• Windows 11 22H2/23H2 Language and Optional Features ISO
• Windows 11 21H2 Language and Optional Features ISO
• Windows Server 2025 Languages and Optional Features ISO
