error: Could not find or load main class C:\TSDZ2- Smart-EBike-1-20.1C\TSDZ2-Smart-EBike-1-20.1C\JavaConfigurator.jar
It's looking for a "class" and mentioning where the error is. JavaConfigurator.jar is in the wrong folder. Every file and folder in:
C:\TSDZ2- Smart-EBike-1-20.1C\TSDZ2-Smart-EBike-1-20.1C
...needs to be extracted and copied or moved into to:
C:\TSDZ2-Smart-EBike-1-20.1C\
It says on the wiki:
4. download or clone the Github repository and unpack in directly to C:\
By that it means that the folder name has to be the same as in the zip file, and be directly on C:\
Here's how that folder looks inside TSDZ2-Smart-EBike-1-20.1C.2.zip, when viewed before unpacking with Winrar:
In this case, that folder name in that .zip file is:
TSDZ2-Smart-EBike-1-20.1C
From here, simply click and hold that folder inside Winrar, and drag it to C:\ then drop. That folder will then be extracted/unpacked from the .zip file and copied directly onto C:\
When you unpack it directly on C:\ the "main class" may be found, because it will be in this folder or subfolder within it:
C:\TSDZ2-Smart-EBike-1-20.1C
Then start the configurator JavaConfigurator.jar which you will find in that folder, and note any error messages.
It's all clearer when using Winrar to extract files and folders, I highly recommend that you download and install Winrar. As I mentioned before, you can also unpack files and folders using Windows 10.
