DO NOT Install Winamp Agent
I just tried uninstalling winamp completely and reinstalled it from same installer, but this time I decided to not install Winamp Agent.
This seems to do the trick, as this time I’m getting no errors at all.

UPDATE: After a few times I used WinAmp the NSCRT.dll file not found error started coming back. So its not the WinAmp Agent, its the AAC audio codec that is messing this NSCRT.dll up. Every time I launch WinAmp the AAC codec is set as default not the mp3. Everything seems to be working just fine if you click through the error, but if you want to use AAC then it might not work. I never use AAC so its no big deal, winamp and the mp3 setting works great for me.
