I am working in an Anaconda environment and have successfully installed PVCAM, PVCAM SDK, and PyVCAM. When I try to run the live_mode.py test, I am seeing the following error:

C:\Users\<user_name>\PyVCAM\pyvcam_wrapper\tests>python live_mode.py
Traceback (most recent call last):
  File "live_mode.py", line 5, in <module>
    from pyvcam import pvc
ImportError: DLL load failed: The operating system cannot run %1.

The following are installed in the environment site-packages:

Please let me know if anymore information is required.

Please provide the PVCAM and PVCAM SDK version you have installed. If the latest version from the website is not installed, please upgrade.

Hi stevebellinger, Installed software versions are: PVCAM: 3.9.5.6 PVCAM SDK: 3.9.3.4

These are the latest as available on the website.

In the past this error has indicated that PyVCAM was built against a different version of the PVCAM .dll then what actually resides in System32. Perhaps pyvcam was built prior to installing the latest versions PVCAM and PVCAM SDK?

Uninstalling, and reinstalling the relevant software and packages in the following order worked:

  1. PVCAM 3.9.5.6
  2. PVCAM SDK 3.9.3.4
  3. PyVCAM

Thanks!
