I understand that FPGA family Stratix II device is supported only with Quartus 18.104.22.168. I have installed QuartusSetup-22.214.171.124.exe for Windows downloaded from the followign link:
Then downloaded "stratix-126.96.36.199.qdz" device family and tried to add device using device installer.
"Can't find Quartus II Subscription Edition device files (.qdz) in directory"
Path of the .qdz is same as required and also license file is added in Quartus software.
Please help. Thanks in advance
Could you try to run the Device Installer as Admin?
If the issue persists, could you try to downloads the Quartus-188.8.131.52-windows.tar from the webpage, unzip it, run the DeviceInstall-184.108.40.206.exe in the /component folder, fill the Quartus installation directory path, and install the devices.
I also faced similar issue, but somehow able to resolve with multiple trials. I noticed that it keep revert back to the default path directory when the error window "Can't find Quartus II Subscription Edition device files (.qdz) in directory" pops out.
