12 years agoV10.0sp1 is an old release, and it did in fact have a lot of installation problems, some related to conflicts with anti-virus software, for example.
Have you tried to install the latest V13.0sp1 instead? Starting with V13.0, Quartus II uses a completely new installer (and new on-demand download center), which is much more robust.
