I have the Programmer for the Unicam Evo ordered me 4.0, because the V23 card of Sky was not recognized by the existing software. First, I have it connected to my laptop with Windows 8.1, but I had to find available USB port, it is apparently not compatible with Windows 8.1 to 2 cable changing and testing at each. So I have me a computer with Windows 7 borrowed, which recognizes the device and after a few minutes, the drivers were already installed. Uploading the latest firmware was very simple. One can find both the software as well as all versions of the firmware on the website of Unicam. The process took less than 5 minutes and provided the desired benefits that I can now use the V23 card in my Technisat.
For the nonexistent compatibility to Windows 8.1, there is a star deduction.
