So I got a new computer and went to install Minecraft on it. I finished running the setup wizard, ran the launcher, and hit play once it finished downloading the game from the launcher. Instead of the game launching, this error popped up.
I tried to reinstall it by removing all the files and running the launcher setup again. It still said it was corrupted afterward. How do I fix this?

According to this Official Minecraft Forum thread on this error:
One solution is to:
Attempt to use the alternative launcher here,

Another is to:
Try to run the MinecraftLauncher.exe found at "C:\Program Files (x86)\Minecraft\" as Administrator.

The file you're looking for is either:
C:\Program Files (x86)\Minecraft\MinecraftLauncher.exe
or:
C:\Program Files\Minecraft\MinecraftLauncher.exe (On 32-bit versions of Windows; it's probably not since you're running Windows 10)
Find that file then right click on it and left click the option labeled 'Run as administrator'.
For me, this turned out to be an internet access issue. Make sure your firewall or any proxy servers aren't blocking it.
