When you installing SDK, did you installing this as user or as root?

[ProudChild]

as a user... but it asked me to enter my "su" password

[mlong]

did you run the installer with "sudo", then?

[ProudChild]

i did the following: Downloaded the offline isntaler, entered as root on the directory, ran chmod u+x [filename] went as a user to my folder, started the isntall process, and then finnaly it asked me the sudo password [cuz im installign in /opt/QtSDK

Hm... it seems like problem with permissions. Can you try install QtSDK to your home dir?
