running programs re-installing

I use the office suite preview of 2010 office (word and outlook) and I use iTunes when launch the programs it has to reinstall why is that? All the time. I use RC1 Win 7

for us to help you, it would be better if you wrote clearer posts.

do you mean that if you launch either word, outlook or itunes, then 'it has to reinstall'?

what does 'it' try to install?

i manage to decipher that as, all the time i open Itunes it gives a message something has to reinstall after installing office 10
