Why can't see the VIP ips in the sopc builder view?

After the installation of Q72 and IP72(full), some of the ips such as the ASI and DDR are listed at the system contents of sopc builder, while the VIP related ips is disappear, what's wrong with the installation?

What does "VIP related ips" mean? 

 You can try deleting the SOPC Builder IP cache: 1) close Quartus/SOPC, open a Windows Explorer window 2) paste this in the address field: %USERPROFILE% 3) delete .altera.quartus folder 4) start Quartus

It means IPs in the Video and Image Processing suite

This method has no effect.
