I have installed the newly released lyx-1.4.1_win32_setup_v1.exe on windows xp-sp2 with all the required programs already installed. It can't detect all the latex components and packages. For example, in the document classes, I can't see the classes beamer, powerdot,.. when I know that they are installed. Surprisingly the test-version lyx-1.4.1_win32_setup_v1.exe works fine and detects the full latex setup.
Looking forward for a reply, Mukhtar
