When I try to install dotnet 3.0 via winetrick,i got a alert box show that " You must use "Turn Windows features on or off" in the control panel to install ....". so it wasn't installed into system.

I just tested this with wine from git and winetricks from svn. Both have recent changes that may have improved things. Seems to be working fine now.

Hi, daniel, my wine version is 1.3.8, and I have gotten the lasted wintricks version. If i set environment to win vista or win 7, the error appear like " You must turn Windows features....", and if I use winxp environment,then the error is " You must install servicepack 2...", I've attached the screenshot below, please pay attend to them. Big thanks
