Troubleshooting: Begin Session Failed Error=80040154

Problem Description.

     Suppose you receive an 80040154 error like the one below when connecting to QuickBooks. In that case, something may have undone your QuickBooks COM registrations (like installing a previous version of QuickBooks or other software).

Solutions

Please uninstall the current version of QuickBooks and re-install QuickBooks.

This should fix the issue.

If you still face the issue, you may try the following solution.

     You can try downloading registerall.zip. And please extract the zip file & run RegisterAllQBDLL.exe.

Right-click on RegisterAllQBDLL.exe & click "Run as administrator."

Please click on yes to run exe.

Please click on RegisterDLL.

It will take some time to run. After completion of the run, you will get a popup message. Please click on the OK button to close the message box.

By running the RegisterAllQBDLL.exe 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 file in the C:\Program Files\Intuit\QuickBooks Premier folder. Just locate the file in Windows Explorer and double-click on it to execute it. This will reset all the QuickBooks COM objects.

     Finally, if that doesn't help, try re-installing QuickBooks. This should have even the most difficult installations going.
