I've been working my way through the tutorial on the Mendix site and I'm about halfway through Stage 5. I'm at the part where it wants me to install the Desktop Modeler. But I can't. I download it and run it and get a message saying "Java Development Kit x64 mandatory prerequisite was not correctly installed." followed by "Mendix 7.20.0 setup ended prematurely because of an error. Your system has not been modified. To install this program at a later time, please run the installation again." Has anyone else run into this? Is the Java stuff supposed to be installed as part of the Desktop Modeler, or am I supposed to have it already? At minimum I'd like to get a handle on whether the problem is on the Mendix end or on my end.
You will need to have installed Java in order to perform a Mendix install - I suggest getting the latest version of Java 8.
