MityCAM Vision Cameras

The dll file takes place of a cti file. Can you share what version of the GenTL viewer you are using? And the python version as well as the version of harvesters?

GenTL Viewer: 2.4.5
Python: 3.8.5
Harvester: 1.3.2

Found an issue with the snap.py and instructions: The viewer installation path changed from "Gentle Viewer" to "GenTL Viewer" so they needed to be updated. Update instructions on wiki and uploaded an updated snap.py. Also fixed the deprecation warnings as well.

Tried using the sim camera but it looks like it's not going to work with harvesters right now. Seems like harvesters doesn't like the XML path we are returning.

It seems as though this issue is linked to using Anaconda's Spyder IDE.
If I run the file from Pycharm or directly from a command line (or in this case: "Anaconda Prompt"), the program complete successfully.

I was able to pick up on the minor instruction typo when originally implementing and did correctly set my path variable. So unfortunately that was not the issue for me.

Thanks for the help.

Final follow up on this issue:

Spyder is fine!
I just needed to restart Spyder to force it to update its environment variables (since I updated the PATH after I had originally opened Spyder).

Glad you got it figured out
