Can't get the teaseviewer working

[MasterOfHyrule]

Yeah so... I hope this is the right place to post this
As the title says I've got a few problems getting the teaseviewer to run. I've done everything as instructed until the point of opening the .jar file - which is the problem. In the list of suggested programs for the .jar file is no java, and I can't find a java file anywhere. So I tried to install Java, which didn't work either. The installation, or more specifically the download done with the .exe from the homepage ran through, suddenly I got an error message that the download failed. That happened 3 times in a row.
So I searched for a program to convert the .jar file into an .exe file and tried to run it - it needed Java.
What am I supposed to do now? Where can I find a Java file and/or how can I properly download Java? Is there an easier way to open the .jar file?
I would very appreciate any help <3

Have you downloaded Java onto your computer?

If it makes you feel better I was trying to open the .jar file with WinRar.

Install the Java Runtime Environment (JRE)
http://www.oracle.com/technetwork/java/ ... 33155.html
(x83 for 32bit systems and x64 for 64bit)

After installation just doubleclick the teaseviewer.jar

Do not try to convert it to an .exe, i don´t think the programm would run without errors^^

That's the problem D: I've downloaded the "jxpiinstall.exe" from the Java website but everytime I ran it at the end of the download it said "Download Error"...
My Internet is down atm (5kbps) so I can't download the one 0131 posted if it is another than the one I previously used. Thanks anyway, I'll post again when I've been able to download it, sorry for making problems ^^"
