You have to download the file in your home directory: www.kegel.com/wine/winetricks Then you type (in the directory where you downloaded it): $ winetricks dotnet11 This should install you the .NET 1.1 and do some workarounds I must add, i have the Novell's version of Suse and it's throwing me a stack overflow too. The first thing I learn from the support of Novell is that the enterprise version does not have the same kernel as OpenSuse, although it's very close in many points. Thus you have to add a grain of salt in what I am saying. If you can, once the .NET is installed, copy the installation file of your software in the drive_c directory of .wine, on the console do $ cd .wine/drive_c $ wine installfile.exe.
