Downloaded vers 1.0.7.0 to my windows 10 computer. Won’t open as stand alone and doesn’t show up in FL Studio or as a soft synth in Acid Pro 7. For stand alone, I get a very brief white screen, then back to desktop.
1.0.8 is the latest version for Windows. But even earlier versions of Vital worked just fine in FL Studio. Try using the VST 2 version not the VST 3 version.
As for the standalone make sure your system meets the minimum requirements to run Vital.
