Set-up MySQL Server on Windows 7 64-bit
It looks like you are creating a New Server Instance Profile, not a New Server Instance.

If you installed MySQL already, then go to the DOS Prompt and run

C:\&gt; net start mysql


or


Click Start
Click Control Panel
Click Administrative Tools
Double Click Services
Right Click on MySQL and Choose Start Service


To verify that MySQL is running on the Windows 7 machine, 


Right Click on Bottom Task Bar and Click Start Task Manager
Click on Processes Tab
Scroll around and Look for the process mysqld


Once you have MySQL running on the Windows machine, you can go to to create a Server Instance Profile. The key here is to install MySQL first.
