Cyclone II Device FIles Missing - Where did they go?

[Altera_Forum]

I started a project yesterday, using the cyclone II device on the ED1 board I have. I open Quartus II today and open the project and is says I need to select a new device since the cyclone II device I have chosen is not installed. Huh? Where did those support device files go and how can I reinstall them? Thanks!

Hi, 

device "support" files are downloadable from altera's website (just go to altera.com => Downloads => webEdition => devices). Nevertheless it's strange that these should have been "lost" - maybe it's worth first to check "which" devices are installed (by selecting a device). Sounds more like there is a config file in the project "wrong"...

Thanks. I took your advice and downloaded all the devices again. That seemed to do the trick. I think I somehow confused the database since I realized I had an older version of Quartus II installed and I think I opened that by mistake. Anyway, I uninstalled the previous version just in case. Hopefully that won't happen again. 

 Thanks!  Mike
