IP Upgrade for PLL fails

I am using our own board

I am running Quartus 18.1 and using a Cypress V

I am trying to run IP that I am using is upgraded.the IP Upgrade Tool. Most of the IP that I am using upgrades, but PLL Intel FPGA v!*.1 does not.

When I create an instance of the PLL using the Megawizard plug in, it works fine and it shows up in the Hierarchy listing and the IP Components listing. When I click on the instance, it does not open the Megawizerd and says that

PLL Intel FPGA v18.1 could not be found in the specified library path

Other IP does open the Megawizard.

What is the issue?
