just installed on a second partitiion, the only thing os might say that he
is already existing, to be direct didnt try it, i dont really think that
might cause any trouble, the best is to do a clean setup .... or on a second
partition. normaly when you reinstall an os you will loose certains *.dll
fies of others applications. instead doing a crapy installation redo it from
the scratch and go for it... just intercept your guinine from the registry
and put back.
