--- Comment #8 from Yolande Haneder yolande@haneder.biz 2008-03-10 02:00:08 --- In my case the .NET is installing fine too on 0.9.56.
The problem is only coming after the registration of the own assemblies of the .NET depending application. I had to make the registration of the assemblies, replace WinSxs for the .NET to fullfil some task and repair the application under the new SXS.
Anyway, I've yesterday just trashed my X-Server. I will have to reinstall the whole Linux and try an unwanted upgrade to 0.9.57.
I've not had any problems with the .NET for month, but anyway I am using another unsupported installation procedure. Gecko is fine on my side. I think it may depend on the distribution or the application.
