When I install the following reference design, Quartus shows "Installation failed" message and stops.
Our Quartus are v19.3 and v18.1, and they both fail.
Other reference design could be installed successfully.
Have you met the same situation?
If yes, could you help to fix it?
Have you installed "Stratix 10" devices in Quartus tool?
There may be some issue with design template, for me also experienced same behavior for one machine but for another machine I could able to workaround like First I downloaded the 'pcie_example_design_18_1_0_222.par' then open Quartus 19.1 Pro & 'Open Project..' & browse the *.par file.
please refer the below screenshot.
