I have the BIBLIOTECA ACADEMICA BILINGUE and can not install the whole thing. I can install the first disk but not disk a and b which contain ALL of my resources. I have been at this for more than a total of 10 hours. Tech support has not been able to figure it out either. I was sent new cds and the problem persists but when i try software that is not logos i have no problem installing. Im running vista 3 gb mem 320 gb hard drive. Any solutions?
