I cannot install ChemDraw 4.5. I get an error message that states: "An unexpected error occurred while installing "blank.cdx" 1008:17,-43 File not found."
On some faster Macs (like the G3 Macs), the ChemDraw Plugin portion of the ChemDraw 4.5 installer is failing. Do a custom install of everything except the ChemDraw Plugin. We have placed a ChemDraw Plugin-only installer on the ChemDraw Files page that will install the ChemDraw Plugin on faster Macs.
