The simple version of the software is not compatible with the Windows 10 operating system. I have checked the official website and it appears you can run DIALux only on Windows XP, Windows Vista, Windows 7, and Windows 8.1. As you can see there is no Windows 10 compatibility, but there is another version called EVO which is compatible with the following versions of Windows: Windows Vista SP2 (32/64 bit), Windows 7 (32/64 bit), Windows 8.1 (32/64 bit), and Windows 10 (32/64 bit).
