Hi Opensim-Team

I just started to use OpenSim and when I try to open my model, the following Error occurs:

Error: In C:\repos\VTK5.10.1\IO\vtkPNGReader.cxx, line 44
vtkPNGReader [0000000011D94830]: Unable to open file C:\Program Files... (can't change the window size to see the full message)

What is wrong here? I use Windows 10, and the latest version of Opensim.

Hi Sandy,

This may because the GUI cannot find some required files. Often this is because the environment variable is not set.

I would find the environment variable OPENSIM_HOME (use a path tool like this one) and make sure that its set to where OpenSim is installed.

let us know how that goes?

Hi James,

Thanks. I installed the tool you recommended, but I could not find this variable. However, I searched for "OPENSIM_HOME" in the registry and found an entry which has the correct path registered. Is there another solution? Would a reinstallation help? Or could the issue be associated with file-permissions?

Hi Sandy,

I had a similar problem after upgrading from v3.1 to v3.3. I solved it as follows:
(1) Open "regedit"
(2) Edit environement variable OPENSIM_HOME from "C:\OpenSim 3.1" to "C:\OpenSim 3.3)
