1- The first thing to do is to open the RUN program in Windows, to do this we use the keyboard shortcut Win + R and type the following “%AppData%“, without quotation marks.
2- A new folder will open in which you will have to look for and eliminate the folder named “.minecraft” or in other cases if you do not have this folder you will have to eliminate the folder “.tlauncher”. After deleting the folder, close this window.

3- The third step consists of going to the Control Panel of Windows and to look for the option that allows us to uninstall programs (Programs > Programs and Features). Here we will have to delete Java and then to install it again.

We will uninstall Java, because it is very probable that you have an outdated or incorrect Java for the version of Windows that you have, you will have to uninstall absolutely everything that says JAVA and then restart the computer.
4- After uninstalling JAVA, we will install it again, for it we will go to the Official page of Java and we will install it from there. To access click on the following link
