Well better news now, QT 4.1.2 F is loadable now, they corrected the corrupted file. But is there any OS 9.1 FU user that tried to load the QT 5 preview 3?
An answer would be nice. I have already loaded the QT 5 Preview 3 installer and i am waiting before installing it.
For a long time, i used QT 4 US on a French OS without a problem after cleanind the doubled files (French and US)
Thanks GRAFF for the tip about Sound Manager and 'Gestionnaire de son).
I cleaned every QT 5 file with Sherlock but i forgot about this one.
