Hello Thanks for your answer I uses the winetricks version available in Ubuntu that is 0.0+20120308 and installed using Code: bash winetricks dotnet40 as described http://appdb.winehq.org/objectManager.php?sClass=version&iId=17886 I think the net 40 is well installed because before the software Captvty could not be launched. Now I can launch it but a part of the window is not filled. [Image: http://pix.toile-libre.org/upload/img/1334433985.png ] There was an improve using Code: winetricks gdiplus but not totally fixed
