it is in the registry, kinda, in the windows uninstall bit you know. for me it has "d:/winamp3/uninst-wa3.exe". I'm not sure if you can get just the directory though. i think you can cause when it says it for me using that key it says "d:/winamp3/" which is good, but i cant get it to be the installdir. im not great at nsis so might need a little guidence
