But as it seems your system is messed up. I recommend to:- uninstall LyX 2beta1 _completely_ - uninstall all other LyX versions (but keep MiKTeX installed) - check that there are no leftovers in the whole registry about LyX - reinstall LyX 1.6.8
Is 1.6.8 really needed when installing beta1-Altinstaller only?
- reinstall LyX 2.0beta1
