I am helping someone install Eclipse Temurin on their computer. I walked though the download/checksum process myself, so I could relay the steps to the user.

My download/checksum process matched. However, on the user's computer it did not. I confirmed the user was going to this web site:

Since I am a new user, I cannot post the link. After the https: // is
adoptium.net/temurin/releases/?version=11

to get the download. I had the user set:
Operation System: Windows
Architecture: x64

The user then downloaded the .msi file. I had the use create a c:\temp folder, and move the .msi file into the c:\temp folder. I walked the user through opening Windows PowerShell (admin). In PowerShell user entered
>cd c:\temp
And the user confirmed the prompt switched to c:\temp
>dir
And the user confirmed the downloaded file was listed
I then had the user run the certUtil to get the hash for a checksum
>certUtil -hashfile OpenJDK11U-jdk_x64_windows_hotspot_11.0.19_7.msi SHA256
The hash on the user's computer does NOT match the checksum values on the web page for the Windows x64 .msi file. When I run it on my computer, the hash does match. We both downloaded the same file yet got different hash results. I had the user re download, re-run the certUtil, and the user gets the same hash, a different one than the one from the web site.

I also had the user send me screen captures so I could confirm the steps were executed correctly.

Why could the user be getting a different hash result? Any help would be greatly appreciated.

I suggest using the Ask a Question link on this page:

https://github.com/adoptium/adoptium-support/issues/new/choose

Or maybe just start a discussion:

https://github.com/adoptium/adoptium-support/discussions

Did you do a (binary) compare of the *.msi you see on your machine versus what the user sees on their machine to confirm they are different as the checksum suggests they are in fact different?
