Finding Machine Identifiers
Hi all!
I'm programming an Excel Add-in and we're wanting to control it's distribution by forcing registration of the add-in. Currently, the registration is stored inside the add-in itself and based on the volume ID number of the C: drive of the machine it's installed on. Whenever it gets copied to another computer, it sees the ID number has changed and resets its registration back to "Free Trial" (there are restrictions on various functions under trial mode). Would it be better to keep track of registration using the system registry since it's unique to every machine? If so, how would I be able to get to it? Or is there a better way to keep track of it? Thanks for your time and assistance. |
