Hello Jakob, are you working in a network environment? In this case, the problem could be related to this and may be solved in the next version: http://www.lyx.org/trac/ticket/8098
Apparently, Windows 7 with network users can be configured to either use the local profile folders (c:\users\...) or a profile folder on the network. In the first case (my current situation), LyX works. In the second (my previous situation), you get problems as described. Unfortunately, I cannot tell you how to change this setting, but you network admins may be able to do that.

However, I have not been able to get lyx running even after searching through the mailing list archives. For example this : http://comments.gmane.org/gmane.editors.lyx.general/64576 I installed Lyx 2.0.3 and Miktex 2.9 on a Windows 7 system today and every time I open a document I get the error message: "The selected document class ...... requires external files that are not available. The class can be used, but not compiled until following prerequisites are installed: ... .cls . See Section Class Availability of the User's Guide for more information" I tried all steps of advice from the discussion above and it is still not running. I have also tried to re-install lyx in case that was the problem. Do you have any ideas what I need to do? Thanks for your help.
