How do I get Arria10 design to compile on Quartus 18.1.2?

Hello Vuk,

I have a workaround for you. Could you please uninstall the patch? Then you have the base of Quartus, install the Arria 10 device.

After you complete this, you can install the patch again and try to compile it again.

To uninstall the patch look follow the next link [1].
