Problem ALTPLL MegaWizzard in 25.1

Hello to all,

today, I upgraded Quartus to version 25.1 (Lite Edition).
Afterwards, I tried to upgrade the IP components.

When starting MegaWizard ALTPLL, a confused dialog box appears. (see attached screenshot)
It's not possible to use it at all.


When I start MegaWizard for the second time, the error message “Failed to launch MegaWizard Plug-In Manager: ALTPLL” appears.

My environment:
- Quartus Prime version 25.1std.0 Build 1129 10/21/2025 SC Lite Edition
- Windows 11 Pro version 25H2

Is there a way to fix this?
Thank you in advance.

Helmut

    Hi FvM,
    ah okay, thank you.
    I had looked for it, but couldn't find anything like that. For whatever reason. Thank you very much.
    Okay, then I guess I can close this request.
