Important points (well, the whole FAQ, but here the points most people skip and shouldn't):
1. Use the latest version of TurboActivate!
2. Notice that on modern Windows TurboActivate can read adapters even if the customer has decided that disabling a network adapter is a useful security protocol (it's not, but try convincing people of that).
3. Running your app as admin and/or runing the TurboActivate as admin will "magically" fix the problem if they're running on soon-to-be-deprecated versions of Windows (Windows 7 and older).
4. If you're still having problems, please provide enough information so that we can actually help you: https://wyday.com/limelm/help/faq/#useful-reports
