Friedrich,

%USERPROFILE% is a runtime variable that takes you to the current user's home directory: C:\Users\USERNAME\
What do you mean never do per-user actions? Because In previous actions of the installer, I make actions in the %%USERPROFILE%%/Documents and it works because it gets the current user that is logged in and does the necessary actions in his/her home directory..

If you say its not possible, what's an alternative to getting the current logged user's home directory in order to do things?

Regards,
