[MOD] Arduino Enhanced Release 1.0.5 for Windows (installer, drivers, etc) +SRC

I am currently using Ver 1.01 on a 64 bit machine can I install this thing separately? or uninstall it if necessary. Perhaps a better question would what affect will it have on my current Arduino environment? I am also looking at that Arduino plugin for Visual Studio, I have your package and the others as well and I am wondering what might be the best path, Fix my current installation?, install Visual Studio and the plug in? Any Advice?
