I've upgraded Quartus ii,from Rev.10.1 to Rev.13.1 .
I'm opening new project with "New Project Wizard".
At some stage I want to select specific device from "Select from Available devices list" option, but this option is an inactive.
The option "Auto select" is active instead.
How can I make "Select from Available devices list" active?
It may happen due to setup a global environment variable 'QUARTUS_ROOTDIR_OVERRIDE' that pointed to a different version of Quartus installed on the machine.
Generally every time quartus launches, it will override the 'QUARTUS_ROOTDIR' environment, but not the 'QUARTUS_ROOTDIR_OVERRIDE' one, which need to be manually changed if a different version of quartus is used.
Go to "System"->"Advanced System settings"->"Environment variable"..
check the "QUARTUS_ROOTDIR" pointing to the Quartus13.1.
The current licence will not work for Quartus 13.1, you need to purchase/upgrade to higher/latest version.
