I ran:
curl https://release.solana.com/v1.8.3/solana-install-init-x86_64-pc-windows-msvc.exe --output C:\solana-install-tmp\solana-install-init.exe --create-dirs
In my Windows command prompt and it showed up like this:

It seemed like it installed - so then I did solana --version and this is what happened:
'solana' is not recognized as an internal or external command, operable program or batch file.
I ran solana --version in Powershell, Git Bash, VS Code Terminal, and Command Prompt and it gives the same output.
How do I install Solana?
Thank you!
