Troubleshooting: QuickBooks & QODBC Reinstall/Uninstall are not working

Problem Description

     I had to re-install QB2007. QODBC stopped working. Reinstallation attempts were not fixing the problem.

     Using QODBC "Test Connection to QB" button returns:

"ODBC32AD.exe - unable to locate component - boost_regex-vc80-mt-p-1_33.dll was not found. Re-installing the application may fix the problem."

     Followed by: "Test connection to QB failed" - QB Begin session failed - Error= 80040154 - Unknown Error

     Uninstalling and re-installing did not help. The uninstall process doesn't do a clean uninstall, however, as it's possible still to access the QODBC driver from the ODBC Administrator panel. Please explain how to do a complete, clean uninstall so that a good reinstallation can be done.

Solutions

     When connecting to QuickBooks, something may have undone your QuickBooks COM registrations (like installing a previous version of QuickBooks). Sorry, boost_regex-vc80-mt-p-1_33.dll is a QuickBooks component. It isn't a QODBC component. So the error is pointing to a QuickBooks problem. To force QODBC to re-install, delete the C:\Program Files\QODBC Driver for QuickBooks folder and re-run the QODBC install the program.

      You can try downloading registerall.zip and running the registerall.VBS script is contained in the zip file. This will re-register all the COM.DLLs in the QuickBooks directory for you. Once that's done, retry connecting.

     If that doesn't work, you can try running the "reboot.bat" file in the c:\Program Files\Intuit\QuickBooks folder. Just locate the file in Windows Explorer and double-click on it to execute it. This will reset all the QuickBooks COM objects.

     If that still does not work, please delete your: C:\Program Files\Common Files\Intuit folder and re-install your copy of QuickBooks as a new install and install QODBC again afterward.

     From there, do the: How to Connect to QuickBooks for the First Time procedure.

     Based on what I've seen on other computers, I'm guessing that parts of a later version of QuickBooks are still in the Common Files folder that you most likely overlooked when you deleted the C:\Program Files\Intuit folder.
