I didn't find solution to do the new LogMein absolutely quite, but i managed to insert All information about my LogmeIn account into MSI file (see one othe post in this thread) so, when MSI runs on user's computer, hi just see the setup wizard, but can't see my account information. To be a little bit more secure, i put MSI inside SFX archive, configured SFX archive to automatically start installation process and then delete the MSI file .
