We had problems when installing certain specific software. To tell the truth, it is a problem that you are unlikely to find yourself. This company uses very specific software, not the the kind that you would find in a regular desktop and many of these programs are unknown to 90% of the population.
Still, sometimes it affects other programs and that's a nightmare.
It is also a nightmare when you have to do a clean installation to a user. When you re-install PGP, since the user already has keys and obviously wants to recover all the encrypted information that was before (or in some other computer), you need him to write his user name and password... but not the current password (users are forced to change their passwords every x months) but the password they used the first time PGP was installed... and nobody remembers that one!
It does have a 5 question system where if you answer 3-4 correctly, it will let you in. These questions and answers are chosen when you install it for the very first time. But suprisingly enough, of course, nobody remember the answer to those either :rolleyes:
On the positive side, I will say that if the user does remember his first password, and you need to pass the data from one HD to another, you can copy the data as it is... no need to decrypt or anything.
