you CANT, and there is no "if" it breaks your system
it's pretty much guaranteed that if you managed to force it to install it WOULD break the system
i can't understand on why you insist on forcing this to install. there's nothing to learn when the outcome is a given
not to be rude but what do you care if I break my system or not .
If you don't know just admit it rather than acting like you know but u wont say. There is not shame in not knowing.
This is a forum where people ask questions and try to get answers not just "you will break your system".
I want to try so let me.
if you know the answer please give it to me otherwise if you don't know or just don't wish to help better you don't reply at all.
for the record I have tried 2009 and it installs and works fine that did not break anything so why would 2007. its just software.
so please either give me the answer I am looking for or don't bother replying.
