Stratix III FPGA Development Kit
Hi,
Thank you for the detailed information.
Since the issue is seen across multiple OS versions, this looks more likely related to the Quartus device package installation rather than the board itself. There is also a similar case where Stratix III did not appear in Quartus 13.1 even though it showed as installed, and the recommendation was to reinstall using the correct .qdz file from the Individual Files tab.

Please try the following:
1. Remove the current Stratix III device support and reinstall using the matching Stratix III .qdz file.
2. Make sure the device installer is pointing to the correct file and folder. Older Quartus II 13.1 cases also showed that device file naming or installation path issues can prevent proper detection.
For reference, Stratix III is a supported device family in Quartus II 13.1, and the EP3SL150 device is part of the Stratix III family.
Regards,
Fakhrul

Dear Support,
I have already tried renaming the device installation file, but the Quartus 13.1 device installer does not accept any name other than "stratixiv-13.1.0.162.qdz". When I use this default name, a window appears with the checkboxes ticked for the Stratix III family (indicating it is already installed). I cannot uncheck these boxes to uninstall only this specific family. I was also careful to place the .qdz file inside a folder with a simple name—without spaces or special characters—as I am aware of this classic Quartus 13.1 bug. Even so, nothing seems to solve the problem, and I am truly at a loss as to what might be going wrong. I am happy to make my machine available for you to take a closer look at the issue using TeamViewer, AnyDesk, or any other remote access tool.

May I know what OS that you are using to install the Quartu 13.1?

Sure, i have tried with all this setups:
1) Windows 11 & Windows 7 (Quartus II 13.1, 13.0, and 12.1 Subscription): Arria and Cyclone families work perfectly. Stratix III shows as installed in the device manager but is unavailable inside Quartus.2) Windows 7 (Quartus II 9.0 Web Edition): The Stratix III family appears in the family selection menu in Quartus, but our specific device (EP3SL150F1152) is listed as unsupported.
3) Ubuntu 12.04 (Quartus II 13.1 Subscription): Same behavior as Windows; the installer claims it is there, but Quartus does not show it.
