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 is only where the synch is actually taking place:

• Workstation - under your user name
• Server - under the dedicated synch user name

You can open two instances of QB on your desktop, but the Intuit SDK won't work when that happens.

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.
