You get the key on the registration web page - no waiting for an email. Registration is tied to the hardware &/or copy of Windows -- if you want/need more than one registered copy you'll need to use multiple email addresses. Digiarty doesn't record IP addresses to limit that. Winxvideo AI, like most AI software, really wants a discreet graphics card rather than an integrated GPU. LM Studio, a front end to run AI models locally on your PC/laptop, proves that ignoring an integrated GPU is an oversight on the part of the devs [shame on them].
Tested the photo option because it's quicker -- obviously takes less time than processing a video. Winxvideo AI 3.0 does work, and is the 1st *general purpose* AI tool I've tested that does. But there's a problem... without resizing, a 4MB jpg image is reduced to <1MB at the 100% quality setting. For the web or emails that might be OK, but it's definitely losing detail when 1/4 of the data goes missing. I had to go into the Properties -> Compatibility -> Change high DPI settings -> High DPI scaling Override & set it to System for Winxvideo AI.exe. And it annoyingly does the AI inference for X2 upscaling as soon as I import an image, so I have to wait until it's done, select the button for image enhancement instead, then go through the inference again. It does max out my lowly RX 6600 graphics card, but it's a bit slower than Topaz AI Denoise, P/Shop's AI, & Luminar Neo's AI.
Installing Winxvideo AI.exe adds the program's folder in Program Files (x86) along with a folder in Users\ [UserName]\ AppData\ Roaming\. Empty folders are also added to Music, Pictures, & Video. The only new registry entry I monitored was a key with the path to the app.
