I am running ChemDraw Ultra 4.5 under Mac OS 8.x and I can't seem to get the Scripts provided with ChemDraw to run. For instance, when I try to run the 1H NMR shifts script, I get the error:

"The script "1H-NMR Shifts" got an error: CS ChemDraw Pro(TM) got an error: <> doesn't understand the <> message."

There are two possibilities.

1. You may have a double installation of the AppleScript extension. Delete one AppleScript extension (System Folder:Extension Folder) and keep the version of AppleScript that came with your Mac OS. Contact Apple to determine which version you should keep for your Mac OS.

2. Rather than a double installation of the AppleScript extension, you may just have an older version installed. Contact Apple to obtain the version of AppleScript that is required for your Mac OS. Otherwise, if you have access to another Mac running the same system software, you can copy the AppleScript extension from the other computer and replace yours with it.
