Yea, sure.

Open the Winamp settings, goto 'Winamp Path' section, press 'Set it' button. It'll open a window for you which able you to set the Winamp directory. Goto your installed winamp directory and select the 'Winamp.exe' and press 'Open' button. If you'd set the right path you will see a message like this: 'Thank You!' and when you see this message you can press the 'OK' button on the winamp settings and you are done, otherwise you must do it again...

I hope this will useful for you :)
