I get this errors when I try to run the executables scripts or the py script files that they use:

I would suggest experimenting with the path to your pcapng file .\caps\vmc12-rcv-SRT-1.pcapng.

I tried moving the pcapng file to the same folder where the exe is as well as removing the "-" characters but I get the same errors

The path must be relative to the directory you are running the script from. Also, check if tshark is available on your system by running e.g. tshark --help.
