I keep receiving the following error message when I try to open OpenSim 2.0

Hi Guilherme,

Please follow the steps described on the forum thread below and let us know how it goes.

Good Luck,

Hi there

I folloewd to the link https://simtk.org/forum/message.php?msg_id=2883
That guided me to https://simtk.org/forum/message.php?msg_id=2723
Than I downloaded the "jre6 update 16" (from http://java.sun.com/javase/downloads/index.jsp), and edited the "opensim.conf" to jdkhome="C:\Program Files\Java\jre6"

Now I am getting the following three errors (at least now, the OpenSim open):

1. An error information window show up
"Required Library failed to load. Check that the dynamics library osimJavaJNI is in your PATH java.lang.UnsatisfiedLinkError: C:\Program Files (x86)\OpensSim 2.0\bin\osimJavaJNI.dll: Can't load IA 32-bit.dll on a AMD 64-bit plataform"

2. And when I open...

3. When I try to open a model

So, Any suggestion?

Regards

Guilherme,

You should use a 32 bit Java VM (even if running on 64 bit m/c). The second assertion is benign and the third is a downstream side-effect of the first one (since the dll's are not loaded).

Try uninstalling the 64-bit JRE and install 32-bit instead and let us know how it goes,

Work perfect
good job!!
thx a lot!
