RE: When Open Windows live messenger(with MP!L installed) doesnt work. It only opens WLM!
You have to install Plus!Live on an account with admin priviledges and make sure nothing is running that prevents writing in the registry when installing (AdWatch, some AV programs etc.).
If in doubt boot into safemode (continuously press F8 on start up) and install on the account called "administrator".
