Mylio does not stay installed

Using Mylio on two different Windows PC. About a month ago, Mylio was deleted off both PCs. I have tried reinstalling the software on both PCs. The software installs, I can run it and connect to my photos, both on the PC and in vault. If I close the software, it will disappear. If I set the PC aside with the software running, it will be gone when I go back to the PC. Any thoughts?

This sounds bizarre. Mylio disappears from where - the screen, or the storage device? Have you tried pressing the Windows key, and then typing ‘Mylio’ (no quotes) to get it to search for Mylio? Is your antivirus system flagging it as infected, perhaps?
