Yes it is, but... now I'm thinking... if I want to install something through my account, I can't... so it means that I'm not an Administrator...? But... if I add an user through cmd in the Administrator account, I have to put: NET LOCALGROUP Administradores BeRniTo /ADD If I try with Administrators, it says "The specified local group doesn't exist.". So, what's going on? Cheers, BeRniTo.
