OpenGL version issue on Windows 10

[tlambert03]

just a thread to track issues related to OpenGL version conflicts on windows 10. Here is a common traceback seen on windows 10 when attempting to show the volume viewer. it seems that windows may have multiple versions of opengl, and is defaulting to an older version with an outdated API.

Traceback (most recent call last):

Just a side note to this: I ran into this issue on Windows 10 when using Remote Desktop to access the machine running spimagine. Turns out that running it locally works just fine.

I'm really not an expert with OpenCL, but I guess that is something to keep in mind when trying to debug this error.

interesting. thanks!
