Hi,
I'm not sure whether it's only related to Demo, but when I wanted to try out the Drafft, Microsoft Defender SmartScreen prevented me from installing the package on my Windows 10 machine. I tried Portable version, but encountered the same problem. Obviously I didn't manage to check out the product.
I doubt it. I can install other applications without appstore and also run portable versions without issues.
I suggest you to submit your app for malware analysis as a software developer: https://www.microsoft.com/en-us/wdsi/filesubmission
Very easy to check really: https://www.virustotal.com/gui/file/f853f2b92f156da7ac13c207a65ba6baea6db32c3246...
Clean as a whistle.
