I already have a subscription to GWizard calculator. Is this app included with it, or would this have to be an additional purchase?
If you already have a subscription for the application, simply browse the official website and download the trial version. After the trial version has been installed, use your registration and unlock the full version of the product. You don't need to pay a second time for the program you have already bought.
