Hi,

I just downloaded OpenSim 3.3 after already downloading and using OpenSim 4.0 to compare results with previous data. I can open the old versions of my models (made in OpenSim 3.0) and even the OpenSim tutorial models, but nothing is coming up on the visualizer.

Is there something I'm doing wrong or a path I need to change? How can I fix this issue?

Hi Eric,

While version 3.3 has no reason to fail on newer machines, the fact is that it was never tested against hardware from the last 4-5 years. OpenSim 3.3 used a visualization package that was few years old so it's very possible that it runs into problems on newer machines. You maybe able to get the 32 bit version of OpenSim 3.3 to run since the x86 platform is likely not being changed much by Microsoft, unfortunately there's nothing we can do on our side to customize the old visualizer.

Please let us know how that goes,
-Ayman
