Windows 8.1 running Cinema 4D Studio R20.030 (RB257898).
Just started C4D from Visual Studio (2015).
Default scene, with Live Selection tool active.
No objects, no materials, no plugins.
Didn't do anything in Cinema 4D, then just closed the application.
R20 was installed without content, only program and help documentation.
The only thing I did after clean install, was set the "Highlight new features" in preferences to "Off". Select the Live Selection tool and then "Window > Customization > Set as Default scene".
I also have created a few custom palettes and saved the custom Layout as startup Layout.
Apart from this, the install is clean ... and never used, apart from starting from Visual Studio to test out some CommandData/GeDialog plugins.
