On Windows 10, I installed MySQL server 5.6 with the VS 2013 integration option. Now when I open the VS2013 Developer Command Prompt, I get:
'MySQL' is not recognized as an internal or external command, operable program or batch file.
I realized it was a %PATH% issue so I added the path to MySQL\bin in HKEY_CURRENT_USER\Environment\Path and re-opened the command prompt. Still got the error. Rebooted the computer. Still got the error.
I re-opened regedit and the path was as I amended it. I went through Environment Variables in System/Advanced settings and the User PATH and System PATH both matched the change I made in the registry.
Weird thing is when I ECHO %PATH% it doesn't match.
