How can I install minecraft without buying it again?

I bought minecraft about 5 months ago and then installed the new windows where it was gone and I want to install it again but I do not know how to do it please help me

Go to https://www.minecraft.net/...net/de-de/

log in
Top left on Download
Download the right version for your Windows, ready.

Your Minecraft is probably just hiding.

Like all other games, after your Windows installation.

Just go search on the internet, maybe you still have your login data.

Then you can download it again on the Minecraft page.

I have my registration data but what do I have to click?

Just download the launcher from the Minecraft website. Start the launcher and then sign up. Minecraft itself is then downloaded at startup.

First you download Minecraft here;

https://www.minecraft.net/.../download/

then you install it and when you open the launcher, a window comes to log in:

Then you can select and play a version as normal.
