What is causing ChemDraw to repeatedly ask to activate or register the software again?


When activating your PerkinElmer product, our server needs to record your activation, and then send a license response to your local machine. A break in this web communication can prevent your local software from receiving this response and recording the license locally. To resolve this issue, from the activation screen, choose More Options and then choose “Deactivate". Once you have successfully deactivated the product, proceed to "activate" the product on-line again.
