You may experience Divide by Zero or Invalid Page Fault errors if your computer is using an older version of a file named Comctrl32.dll

There is a fix. The Cakewalk 7.0 CD contains a file called 40Comupd.exe. (The Setup routine should have detected the older file and asked if you want to update
Comctrl32.dll. It's possible that you clicked No or the Install routine somehow missed the old file.) Updating the required file on your computer is easy.
1. Browse the Cakewalk 7.0 CD using Windows Explorer.
2. Open the Cakewalk directory
3. Double-click the file called 40Comupd.exe. This will update your Comctrl32.dll file and restore Cakewalk to full operation.
