when something goes wrong, give user call to action / report of what went wrong

I attempted to install from Setup-bundled-0.0.2-20160401-33.exe and while the installer was OK with my using my pre-installed JDK 8 in C:\Program Files\Java\jdk1.8.0_25 (or C:\Program Files\Java\jre1.8.0_25) it then ran into a problem using that JDK to install JBDS.

I noticed the problem at about 12% on the progress bar but it was still moving along at 45% when I grabbed the screenshot (attached).

If a failure occurs, perhaps we could change the bar from blue to red and move it to 100% ?

Also, should there be a call to action for the user?

Even something simple like "go check in C:\DeveloperPlatform\install.log for what might have happened" would be useful here.
