i had an official version of office 2021 pro installed. now bought the 2024 version.
i un-installed all components of 2021, did new install - activated by website - cleaned previous non-active license : all ok
today i open access again and see in account version 2021 again not activated and activation required.
i downloaded Microsoft Support and Recovery Assistant as indicated on support page of MS
running these commands indicates : no version of office detected/found
how can I get a clean install of 2024 and how to remove all history to 2021 version ?
if i look in control panel - installed programs : i only see the installed version of 2024 : microsoft office ltsc prof plus 2024
i also started the only repair function in this page
best regards, Guy

I'm not sure I understand. Office 2024 LTSC is the volume license version of Office 2024, not the Retail version.

You normally have to use the Office Deploy tools to install.

i bought this license in an online shop
i received the license code to enter at registration/activation
when I executed the command to see the status : it indicated ltsc
looking now isee : LICENSE DESCRIPTION: Office 24, RETAIL(MAK) channel
but if i look in any product of office in account : i still see 2021

I think you are still using a Volume License version.

Some similar threads on the Microsoft Q&A forum. But I'm not clear on the solution found (if any).
