Today I run my MinecraftLauncher on my X64 win10 PC then get error dialog :"unable to Update the minecraft Native Launcher" ,then I try to resolve the problem by delete the whole MinecraftLauncher directory on my disk .then I download the Minecraftinstaller.msi from the official site and install it .When all is finished,I open the MinecraftLauncher.exe but get an error dialog: "Unable to start the Minecraft Runtime Environment.This is most likely caused by a corruption. Please try to reinstall minecraft",then I try to uninstall then reinstall, but it still not work.then I search this problem in the internet, the solution was not fine.so I try to resolve this problem by myself, I found that the MinecraftLauncher creates a directory in C:/Users/who/AppData/Roaming/.minecraft and regiester a key"HKEY_CURRENT_USER\Software\Mojang" in the windows registry. some special cases the MinecraftUninstaller will not remove these things, so the minecraft launcher error again and again, I try to delete these tow things on my computer then use the MinecraftInstaller.msi to install the launcher, run the launcher it's worked.
If you are in ths trouble like me The Key Steps for can resolve:
1.use the MinecraftInstaller.msi to remove the launcher.
2.delete the C:/Users/who/AppData/Roaming/.minecraft directory.(by default the AppData directory is hidden you should make it visible)
3.delete the KEY HKEY_CURRENT_USER\Software\Mojang in Windows registry.(press win+R at the desktop then type regedit to edit the registry)
4.reinstall the MinecraftLauncher by MinecraftInstaller.msi
5.double click the MinecraftLauncher.exe or right click run as Administator.
