right click the installerpackage > Click Properties > choose the Compatibility tab > check the box “Run this program in compatibility mode for:” and choose Windows 8.
Afterwards simply start the setup again and it will install
Here I installed it without setting compatiblity mode with no problems. But after some time using, it aways messes Windows Explorer causing a lot of glitches and freezes (see image). I aways had to manually restart the explorer process. Changing GlassWire.exe to Windows 8 compatibility mode fixed the issue with Windows Explorer.
Well, actually I was wrong. Launching it in any compatibilty mode doesn’t fix the problem for me. It only took longer to crash Windows Explorer. Unfortunatly, I can’t use GlassWire if I don’t want to have to restart Windows Explorer every once in a while.
