Now I want to use parameters STRAP and SINTENSITY in both instances. But one instance executes fine, and another with error:
Driver is in use, try to start miner with "-driver uninstall" parameter.

Question: how to use one driver name in one instance and another driver name in other instance?

I have 2, 3, 4 instances of Miner and parameters STRAP and SINTENSITY need to in all instances.
