Hi,
I follow the install instruction on picoquant.github. I finished all the steps, but when I ran a demo file, I got the error from cmd below

C:\Users\admin\Downloads\snAPI-main\demos>python Demo_TimeTrace.py
Switched to: TkAgg
Error in sys.excepthook:
Traceback (most recent call last):
File "C:\Users\admin\AppData\Local\Programs\Python\Python312\Lib\site-packages\snAPI\Main.py", line 292, in logException
dll.logError(f"Uncaught python exception: {exception_type.name}!".encode('utf-8'))
OSError: exception: access violation reading 0x0000000000000000

Original exception was:
Traceback (most recent call last):

sn = snAPI()
^^^^^^^

Fixed, there are some issues with dll library. Reinstall different Microsoft Visual C++ Redistributable(x64).
