Well, I have finished my analysis of Libronix with CrossOver 7.0.1. As far as I can tell, little has changed with performance and installation with Libronix 3.x. I have tested with each bottle and had a variety of results:
Win98
Installation into the Win98 bottle is much the same as with previous Cxoffice versions. You must still install IE6 before anything else. You should also install the fonts, since it seems like there are some font issues. I am not sure if installing the core fonts changes anything, but some dialogues are readable while others are not. After the installation of IE, you can easily install Libronix, though it appears you should not select the setup file in the root of the cd drive. Rather you should go to /Setup/Installs and select DLSSetup.exe. Otherwise you may get a message saying, "You must run Libronix Update first..." Alternatively, you could just select "Run Windows Command" from the Crossover linux menu and select the setup.exe file (it seems to work fine this way).
Once installation is underway, the process seems to complete without a hitch. It is only when you run the newly installed program that you realize that something is wrong. Once running Libronix seems to have the same old problem as before: A blank screen with no GUI; just a grey workspace. Keyboard shortcuts work okay and you can even access your library using ctrl+l. Resources open fine, but everything else appears broken.
Windows 2000
Installation into the Windows 2000 bottle did not seem to work too well. It progresses as far as the Libronix Update stage of the installation but seems to hang from there. These seems like an improvement from the last version of Crossover.
WinXP/VISTA
The challenging part with the XP and VISTA bottles is that IE6 does not like to install. If one could progress beyond this by installing IE 7 or perhaps 8 you might be able to succeed. The wine version that is setup with the XP and VISTA bottles does not seem to work. It loads, but is blank.
Since one cannot proceed to the Libronix installation until IE has been installed successfully, there is little hope for success.
Installation of Libronix 2.x with Crossover
As it has been previously, if you have a 2.x version of Libronix you can install into a Win98 Bottle without an problems. The GUI is visible and nearly all the important functionality is there. Though a few features are broken, you can still work with the program so long as you don't need to use lemma density graphs, and some of the more advanced features.
