About using the Protection Key
Earlier versions of XCom v2.2.13.26 (2009-12-10) included the H / W Protection key.
However, since v2.2.13.26 (2009-12-10) separated XCom and the protection driver, the protection driver must be installed separately.
XCom checks the protection key even during startup. Therefore, do not remove the H / W key while the application using XCom is running.
There are two types of protection keys currently provided: printer port and USB.
