Recently I got a new and better laptop to play games on. I had very recently bought Minecraft For Windows 10 through the Minecraft Launcher on my OLD laptop. However, when signing into my Microsoft account with the Minecraft Launcher on my NEW laptop, instead of the "Install" button being there, it's telling me I have to buy the game again.

I have done research about this issue online and the only thing that came close were some people not being able to install their Minecraft copy when Microsoft started doing this whole switch from Mojang to Microsoft account's thing.

Apart from that, I've found no information on the subject, and I really do not want to have to spend another $29.99 dollars on this game.
