before formatting the PC, what about the license?

I ́ll format my PC where I have installed emClient Pro with its activated license. Which is the correct procedure to keep the license activated without problems after the new OS installation? Do I have to deactivate the license prior the formatting? Thanks.

Best to deactivate. Menu/help/license and click deactivate. If you don’t know or lost your key, go to http://www.emclient.com/lost-activati…, enter the email address you used for registration and they will resend you the key.

Hello,
since formatting can change the HW ID it’s best to deactivate the license before it, just as Jay describes, and then activate it again when you’re done.

Jay and Olivia,
Thank you for the responses. It ́s clear.
