version 3.0.1 has no wizard and does not support more cameras than version 3.1. If the wizard of 3.1 does not detect your camera then it means that it is probably not supported by version 3.1 and will not be neither by version 3.0.
You can skip the wizard by clicking the Cancel in the lower right corner and configure cam2pc 3.1 by hand as you would have configured cam2pc 3.0.
