Hi All, Well, I have managed to get LyX installed more or less onto W2K, with some help from Claus. It is working, it is not crashing when I hit a key, and so on. But ... there is still one glitch ... I have files that I created on LyX on Linux, and tried to edit them on W2K ... but it didn't work out. I was told that the document class didn't exist ... and when I tried to alter line-spacing I ended up being told that some style file (linespace.sty (or something like that)) did not exist. OK. I installed all MikTeX levels up to level 4, and I tried to reconfigure LyX, using the batch file for this puporse. But still no joy! How do I get LyX on W2K to recognise new style files, and document classes? It there some instruction somewhere? Some advice? Thanks Regards Freddo PS I will write a little summary of my experiences and post them in the next day or two, so others will be spared my trouble. (I do think though that the horrible problems that occur because of W2K accepting spaces in file and directory names ... I mean because MikTeX in the English version installs into 'Program Files' by default for example ... this should be mentioned in the documentation.)
