Same situation: Ubuntu 10.04, Mono 2.6.7 with all the dependencies satisfied, but I still have errors on boot.
If someone can help us, I'll provide the errors that the terminal gives me.
If I don't remember wrong, Dr.Clipper updated the .Net versions, some releases ago, right? Could it be this the problem?
In the best "wiitaly"an forum, we've solved just installing from Ubuntu Software Centre
Code:
libmono-microsoft-visualbasic8.0-cil
then go into the Configurator folder and type:
CODEmono CfgLoaderConfigurator.exe
