Unfortunately, if you want to use StrikeRisk 5.0 on several computers, you need to purchase multiple licenses. You can use the USB unit to activate the product only on a single PC. I suggest you contact the developer for further information. Also, if the USB dongle is not recognized, press Windows + R key combination, type devmgmt.msc and click OK. Expand the Universal Serial Bus controllers list, right-click on the driver and select Uninstall. After that, reboot your computer, press Scan for hardware changes icon from Device Manager and wait for Windows to retrieve the drivers.
Note: If you have a red dongle (used for multiple computers), you can use the instructions from the official user guide, in order to activate the product.
