ChemDraw crashes when I try to launch it.
Some versions of the the ObjectSupportLib extension can cause a crash. Another program may have installed an older version of this extension. Try removing this extension from your Extensions folder, and then do a Custom Install of this extension using our installer.
System 8 users do not need the ObjectSupportLib extension. It is built into the OS. If you have this extension in your System Extensions folder, delete it and then try ChemDraw again.
