Problems installing (under win10)

[E.T.]

Hi, I'm a (hopefully, future) new user, but I'm having trouble with the installation.
The installer stops with an error message about the variable EXE4J_JAVA_HOME. I define it to point to the jre1.8.0_91 directory and then the installer complains that the JVM found there is damaged and cannot be executed, although the Java test says everything is OK (which is presently the only thing I know how to do with Java, I'm afraid).
Thanks for your help!

ET,

Here are some questions and comments that should help us determine the problem:

Did the JRE install successfully from www.java.com? The installation includes a procedure to confirm the installation -- did it confirm correctly? Did you install the 32- or 64-bit version of the JRE?

Once the JRE is installed, all you need to do to run JaamSim is the double click on the executable you downloaded from http://jaamsim.com/downloads.html. There is no installation program for JaamSim -- you just copy the executable to the folder in which you intend to build your model. On Windows, its easier to use the executable (.exe) instead of the jar file (.jar). If there is any question of whether you installed the 32- or 64-bit version of the JRE, try both versions of JaamSim.

Are you trying to build JaamSim from GitHub? There is no need to do this unless you want to program new functionality.

Yes, it confirmed correctly, the 64-bit version.
I'm using the executable (although the next thing I'll try is to install under ubuntu 14.04, and for that I believe the jar is needed).
I'm still far away from the position to (contribute and) build it from GitHub - actually, it is in the status "I wish some (future) student eventually wishes" ;-)

Already working under ubuntu... +1

You can also use the jar file under Windows, it actually works on all
three of Linux, OSX and Windows.

On the command line:

java -jar JaamSim2016-11.jar

This will at least narrow the fault down to it being a java
installation problem, or a problem with the exe-wrapper we use to
package jaamsim as a windows executable.

It would be great if you could test the above.

Sure! I'll do it tomorrow, my win10 is at the office (and I use ubuntu at home).
(I've already tried a first example from the user manual, it looks very nice, and promising.)
Thanks a lot!

Hi Harry, Harvey and ET

All three versions of JaamSim run fine on my Win 10.

Mike

[E.T.]

Done, and it works fine.

Therefore, both JaamSim and the JRE are working, the only problem (in my computer, or in my (spanish) version of win10) is with the exe instal4j, and it might be rather anecdotal, so never mind.

Again, thanks a lot for your prompt help!

E.T.,

The problem with your work computer is not Windows 10 or the fact that it a Spanish version. The most likely cause is a security setting that prevents the wrapper utility exe4j used in the .exe version of JaamSim from setting up its temp folder. The easiest solution is to use the jar file, as you've discovered. On most Windows computers you can double-click on the jar file to launch it. Students who are using their own computers won't have this problem and can use the .exe version if they prefer.
