To be able to use Hintpad Windows, it is mandatory to install Java. 

Option 1: OpenJDK 

This option requires a little bit more work to be installed, but is an open source program that can be used for free in a commercial use device. Therefore, we recommend this program.

Option 2: Oracle Java. 

This option is easier to install, but it needs a paid licence to be used for commercial purposes.
