Quartus Prime Pro 21.2 - cannot install devices - Quartus Prime Pro 21.2 - cannot install devices Hi, I just installed Quartus Prime Pro 21.2. The installation archive includes some device files (.qdz files) but when I try to install them, I get an error: 'The device files (.qdz) in the directory ... doens't match the version of this installer.' Can anyone suggest a work-around?
