On the right side of the tool or menu bar I'm missing some of the buttons / icons.
This would indicate one of two things.
1. The ChemDraw application window is not maximized. If the ChemDraw window is not fully maximized, all of the buttons will not fit in the area provided to display them. Click on the "Maximize" button (the middle one) for the ChemDraw window.
2. It could also be that your monitor settings are set up such that you cannot see them. If your screen settings are set to a low resolution like 640x480 or even 800x600 and depending on the size of your monitor, you will not see these items because there is not enough room to display them. Try setting your display resolution to something higher like 1024x768. This is done in the Windows Display control panel.
