>Manual install as well on these shows no spesific error.
<<How did you install manually such as install Office from portal?
Do you mean that there is no response after installing manually?
I use the xml given above to do the test, successfully change Microsoft 365 Apps installation from 32-bit to 64-bit.
Are these Windows operating system 32-bit?
If they are 32-bit, it would be impossible to install 64-bit Office.
