Thanks for the screenshot.
I found some users with the same behavior you reported. The software should have been installed together with the driver because it is bundled with the driver.
The manual installation procedure is complicated because it requires extracting the original installer. That's why I extracted it here and will share the file with you.
Download the Intel Graphics Software installation file from the link below.

(This link I'm sharing with you is straight from my OneDrive. I needed to extract this file from the driver installer I suggested earlier.)
(Run the downloaded EXE file and follow the on-screen instructions to install it.)
Let me know the result. Click on the "Reply" button below my reply.
Feel free to ask back any questions.
