I had installed the new minecraft launcher for windows 10 but (i have windows 10) when i tried to open it, nothing has happened, so i have tried to uninstall it and reinstall it but nothing has changed, so i have tried to uninstall both launchers, the "normal" and the "new". Now i am trying to reinstall the "normal" launcher but if i click on the installer, it doesn't download the launcher but it opnes an empty "xbox installer" tab where i cant do anything. What should I do?
