Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello,
I understand that you’ve already tried several troubleshooting steps without success. Please note that the instructions we provided were only for installing the program, not for activation.
Moving forward, I believe there might be an issue with your operating system itself, which is causing the installation problems. In this case, we can try a repair upgrade, which will fix existing system files while keeping your files, apps, and settings intact. To do a repair upgrade, go to

Run the tool.
Select Create installation media for another PC.
Select language and edition.
Then, select the ISO file and save it to your local drive.
Once downloaded, mount the ISO file and run the setup directly from the explorer.
Windows installation will begin. Follow the on-screen instructions to complete the installation.
Once the repair upgrade is complete, try installing the Office apps again. Here's how to install Office apps on your device -
Download, install, or reinstall Microsoft 365 or Office 2024 on a PC
Let me know how it goes.
