When you successfully run latex at a command prompt, you are doing so with the limited rights account, correct?
Am I correct in assuming that if you log in with the local admin account, LyX works correctly for you? One thing you might try is to delete the local LyX directory for the limited rights user, then restart LyX (as the limited rights user) and let it try to rebuild that directory. I think the directory is usually stored at C:\Documents and Settings\<limited rights user id>\Application Data\lyx. (Unfortunately I don't have access to a Win XP machine anymore.) Just delete the entire directory. I you have modified any bind or layout files, you might want to back those up first, but if this is an out-of-the-box LyX installation there is nothing there you need to worry about. Paul
