Answer 1

Hi @Anurag Singh ,

Welcome to Microsoft Q&A!
This is a generic error. It seems to be a problem with your system environment variables. You can refer to this picture to check if you have too long or multiple duplicate Paths in your environment variables.

If you can't see it clearly, you can also view the Path by accessing the registry.

• Check the length of the Path variable by pasting it into a word document and check the character count.
• See this thread about shorting the character count.
• Reboot your PC
  In addition, This will also occur when the “FIPS-compliant algorithms” policy is enabled on a system.
  Disable FIPS setting: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy]
  “Enabled”=dword:00000000

Best regards,
Seeya

Answer 2

SQL Developer edition is compatible with the Windows 11 and I believe there is a issue with the media.
Did you get it from the official and trusted source?
Make sure update your Windows and restart your PC and try again.

So you get this error when you select Download Media? I don't know what is going on, but the prime guess is that there is a network issue. It could also be an over-zealous anti-malware product that strikes.

I wold try a different network channel if possible, and also a different computer.
