We have a legacy design that uses purchased IP supported on Quartus II 15.0 but not on 16.0 and later versions. We need to be able to support this product. With support for Windows 7 ending, can we run Quartus II 15.0 on Windows 10, or will we have to keep a Windows 7 system to be able to support this product?
Incidentally, it is impossible to find OS support information on the Intel website for older versions of Quartus.
Windows 10 is not supported for Quartus 15.0. However, You can use windows 8.1 or red hat Linux 6.5.
