Fail to install 2004 upgrade
Hello,
I am still on windows version 1909! and windows update don't propose 2004 upgrade ,it says " you are up to date "
So I tried both " Media control tool 2004" and "Windows10upgrade9252" but at the end of all the process I always get this message "Installation program validation of product key failed"
I search solutions everywere and even bought a new windows 10 pro key, and replace it, with no difference!
I am connected with a microsoft account and it says " Windows is activated with a numeric licence coupled with your microsoft account "
I also tried with a new normal account! same end!
Can you help me to resolve this mess ?
thank you
sorry for my english
windows version : 18363.900
