I am trying to launch the version of ChemDraw that comes on my SigmaPlot CD-ROM, but it states that the serial number and/or registration code are incorrect. What do I do?

Please note that SigmaPlot and ChemDraw are made by two separate companies. SPSS makes SigmaPlot, which has its own set of codes for installing. We (CambridgeSoft) make ChemDraw, which also has its own separate set of codes for installing (see the ReadMe first card).

First make sure that you are not trying to install ChemDraw with the codes for SigmaPlot. To install ChemDraw, you need to use the codes on the ReadMe First card. However, due to a shipping error, the wrong ChemDraw Std 3.5 codes were sent with some SigmaPlot CD-ROMs. If your ReadMe First card indicates that you have ChemOffice Ltd 4.5, and not ChemDraw 3.5, please fill out the following form, so that we can provide you with the correct codes.
