Quartus Prime Standard v21.1: Failed to launch MegaWizard Plug-In Manager

[NJackson]

I have instantiated a PLL in a project using v21.1 of Quartus Prime Standard Edition.

When I try to reopen the PLL to edit the settings I get the following message:

"Failed to launch megawizard plug-in manager. PLL Intel FPGA v21.1 could not be found in the specified library paths"

When I look at the pll_wizard.lst I note that there is no entry in the <ALIAS> lines for v21.1 (file attached). Should I hand edit this file to place an ALIAS for v21.1?

So this is a new PLL instance that you just successfully generated, and when you try to reopen the parameter editor for it, you get that error?  Or are you saying that you instantiated an old PLL instance that you've created previously and are trying to bring into 21.1?  What device does your project target?

Try recreating the PLL from scratch from the IP Catalog.

This is a new PLL instance that I have successfully generated.

I edited the pll_wizard.lst file to add the line: 

<ALIAS>PLL Intel FPGA IP v21.1</ALIAS>

 After that I was able to successfully modify the PLL. 

I guess this file wasn't updated as part of the uprevision from v20.1 to v21.1.
