I am having problem installing Ufile for Windows 2020 on my desktop. I downloaded the Ufile2020.exe file to my Desktop, when I tried to open the file, nothing happened. I then tried right click on the file and select Run as Administrator, User Account Control came back with a message saying "Do you want to allow this app to make changes to your device?" I clicked Yes, then it just disappear. My desktop is running Windows 10.
