How do I get the Minifier to Work?

I think the Script Minifier is a great idea. However, I have not once managed to get it to work. Here's my Java version output:

C:\Windows\system32>java -version
java version "1.8.0_77"
Java(TM) SE Runtime Environment (build 1.8.0_77-b03)
Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)[/code:3fyf99cs]

But this is the error I get every time I export the game for testing on a web server:

What am I not doing / doing wrong?

I had to restart Construct2 after the Java installation - then it worked for me.

Thank you very much for your reply! I should have done that before whining... Of course, it worked, thank you!

Always getting this message.

First I had only java 8 32bit, then instaled additionaly 64bit version, then uninstaled 32 version...

At every point made a restart, and nothing helped.

Now I have:

Java 8 (x86) update 92,

Java 8 (64 bit) update 92,

Windows 7 (64 bit) professional,

Construct 2 (64 bit) r225

Intel i5-3470 3.20GHz 3.20GHz

RAM 16.0 GB
