Error 80040438 - Multiple QuickBooks running | CLEARIFY

Correcting Error Code 80040438

There is an error in the log similar to this:

Cause

This comes directly from the Intuit Software Development Kit (SDK) and indicates that it is unable to continue, because it sees two instances of QBW32.EXE running.

This includes running a second instance of QuickBooks while the synch with another file is running - including different versions of QuickBooks.

Resolution

Make sure that only one instance of QuickBooks is running when attempting a synch.  If you are uncertain, run the Task Manager to ensure that another instance of QBW32.EXE is not running
