It normally came with a CD that contains the driver and also here's a link for it. Driver and Firmware for PC Adapter USB 1.2 Hope this helps.

I suggest you to start with Working with STEP 7 V5.4 Getting Started. Also you could use "inbuild" manuals in Step7 installation directory (bassically this is C:\Program Files\Siemens\Documentation\English) Best regards, Hristo Mihalev

Hello, You should install Authorization on harddisk. Perhaps this link might help: how do you install, uninstall and upgrade authorizations? Best regards, Wizard

If you've installed Step7 recently (Fresh install), you have a trial license of 14 days. You can activate it on starting Step7
