As mentioned in the comment by Smithyk, disappointingly this appears to be a fairly crippled version. Immediately after the installation (which I had no trouble registering) I was informed that “the giveaway version doesn’t support unlimited video/image enhancement features” and was prompted to purchase the full “lifetime” version. Restrictions in this free demo version include: upscale videos to only HD; increase video frame rates to only 60fps; stabilization has file size limitations; video & audio download limited to 300 sites (full version offers 1000+ sites); the cut/trim/combine, add effect/subtitle, correct color, remove fish-eye, make GIF etc feature offers “basic editing only”.
Hence, many of the features mentioned on SharewareOnSale’s description apply only to the paid version, NOT this giveaway version.
