It seems to fail with the following error in console:

And of course, the class doesn't exist.

Post the full install log from the console. Those classes exist just fine.

I've also done a bit of googling, it seems others are having this issue with the latest 1.6.2 version. The class just doesn't exist.

 

And is there a installation log? Because I'm not installing it again..

Installing is 1 click, just do it.

There is no log file.

And that class DOES exist. So you should be doing something wrong.

I know it is one click, but that doesn't mean it takes one minute (17 minutes on my machine).

 

And the class doesn't exist for me.

 

Consdiering you're in the wrong package...

Im not sure what you're trying to show with that screen shot.

Also, showing the ERROR in eclipse *might* be helpful as errors usually mean something is wrong -.-

And who cares how long it takes? Click it, let it run, go take a piss come back its done.

Thanks for reminding me I was in the wrong package. Considering the class actually DOES exist, I think its a eclipse issue.
