If you are working on this bug, if it is a bug, I will indicate that I was running Ubuntu Linux 9.10 and there was some Microsoft +Net 2.0 that Slingbox installed or attempted to install. For some reason +Net failed, but SlingPlayer continued to install itself.
You should install .NET before running application installer. Use 'winetricks dotnet20' to do it properly (http://www.kegel.com/wine/winetricks).
