I have tried several times to install Versatune on my car and keep getting the attached error every time during the backing up of the stock tune portion.
I've done everything as the instructions say.

What car do you have? Do you currently have an aftermarket tune on the ECU? Does it fail right away or somewhere in the middle?

Then you probably have some other device connected to the CAN bus or the OBD-II port of the vehicle. Gauges, loggers, alarms, modules that keep the lights or radio on. Common culprits are devices made by MX-5 Things.
You will need to disconnect them temporarily while you are reflashing the ECU.

There's not much we can do. Those devices constantly query the ECU and interfere with the flash process. They will interfere with any tuning solution you decide to use. You don't need to completely remove them. Just disconnect them from power or from the CAN bus for 1 hour while you reflash the ECU.
