Minecraft gives 'Unable to update the Minecraft Native Launcher' when updating to v1.9

Solution 1:

I there is a version of Minecraft that is made for new Windows. To get it you go to the official website at https://minecraft.net/en/download/. When you go there you can find a link that says:

Try an alternative download.

On the page that opens you should see a link named Minecraft.exe. Just click that, then it will download and you should be all good.

Here is a screenshot of the download link:

As far as I can tell I am the only person who did not get the new launcher for Windows 10.

Solution 2:

It's Java, I just fixed that problem.

Uninstall old versions of Java (you can get the uninstaller from their website) and then install the new version. The updater then works fine.
