Sorry to hear. Sounds like something is wrong with either the windows store/app or your installation. 0x800700b7 seems a fairly generic error to do with file conflicts. I've just tried on an up to date windows 10 installation and it installed filelight just fine. I suggest you try a windows support forum to figure out what's wrong with your installation https://answers.microsoft.com/
