Troubleshooting: QB Open Connection Failed. Error = 8004042f

Problem Description

    When trying to connect to the Australian QuickBooks file (version 2007/08 trial) and getting the following error.

Test Connection to QuickBooks Failed.

[QODBC] QB Open Connection Failed. Error = 8004042f, The requested connection type could not be found.

Solutions

It would help if you had QuickBooks installed on the machine on which QODBC is installed.

If you already have installed QuickBooks and are still facing the issue, please reinstall QuickBooks.

QuickBooks Trial Edition:

   Your trial version of QuickBooks must be registered with Quicken before QuickBooks will allow integrated applications to access it. Once you have QuickBooks written, follow the: How to Connect to QuickBooks for the First Time to connect again.

     If your trial version is registered, you might have chosen to install a QuickBooks flavor that's not communicating with the SDK. The workaround for this is simple -- if you go to your QuickBooks program files directory and COPY qbw32.exe to qbw32<flavor>.exe where <flavor> is the flavor of QuickBooks you have installed:

Pro
Premier
PremierAccountant
PremierContractor
etc.

     Then your QODBC connection issue should go away.

     For example, if you have QB Premier, contractor edition installed, then you would copy QBW32.exe to QBW32PremierContractor.exe in the QuickBooks program files directory, etc., as per below:

qbw32premieraccountant.exe
qbw32premiercontractor.exe
qbw32premiergeneric.exe
qbw32premiernonprofit.exe
qbw32premierprofessional.exe
qbw32premierretail.exe
qbw32premierwholesale.exe
qbw32pro.exe
qbw32simplestart.exe

QODBC Instruction

     QODBC is a fully functional ODBC driver for reading and writing QuickBooks Pro, Premier, Accountant, and Enterprise accounting data files. QODBC doesn't work with QuickBooks Easy Start, Accounting (formally known as Lite), Plus, or Small Business Editions.

     BTW: The Australian version of QuickBooks also doesn't support Integrated Applications like QODBC on Microsoft Windows Vista operating systems. You must use QuickBooks on Windows XP or Windows 2003 platforms.
