The serial number that needs to be entered here should be supplied to you by an administrator, your IT department or by the person who initially purchased Adobe InCopy for your company. (Also note that the serial number will be specific to the version of InCopy you have purchased; CS5, CS5.5 or CS6. It is also language and operating system specific and will only work on the appropriate version of the software.)
If your company already has a serial number please contact your project manager or your IT department who should be able to supply you with the appropriate license. If they are unable to help you, and your company has purchased InCopy directly from CtrlPrint, please contact CtrlPrint support who will be able to supply you with the correct serial number. If your company has purchased InCopy from a vendor other than CtrlPrint you will need to contact them for assistance.
If you need a serial number, and your company has not yet purchased one, you can buy a license from CtrlPrint by contacting our sales department. Their contact details can be found here.
