QuickBooks Desktop Error Messages

Check the "qbsdklog.txt" file for possible additional information.

Checking the "qbsdklog.txt"


You run the sync. In the Connex log, you get an error saying to check the QBSDK log file.

How do I send the log to you?

First take a look to see if there is a qbskdlog.txt file. If there is, rename this file to qbsdklogold.txt.

For Windows 7, 8, and 10, go to c:\ProgramData\Intuit\QuickBooks and edit the qbsdk.ini file.

For Windows XP and Vista, go to c:\Documents and Settings\All Users\Application Data\Intuit\QuickBooks and edit the qbsdk.ini file.

Add/Edit the following lines:


Restart QuickBooks and run the import that causes the problems.

Zip and upload the qbsdklog.txt file in this folder and send to Transaction Pro Support at support@transactionpro.com.


Multiple Versions of QuickBooks

This error can occur, if you have two versions of QuickBooks on the same machine. If you have QuickBooks Enterprise 2018 and QuickBooks Enterprise 2019, the sync can fail because our tool fails to locate your company file and the proper version of QuickBooks. If you upgrade QuickBooks, then uninstall the older version.

Since some users run QuickBooks 2018 and you are running 2019, you will receive this error at times:

The application trying to connect to QuickBooks is not supported while multiple instances of QuickBooks are running

If you pull the SDK log in the error, you could see this entry:

Could not find or create an instance of QuickBooks using InstanceFinder

To remedy this issue, uninstall all versions of QuickBooks completely from your computer. Perform a fresh install of the latest version of QuickBooks available to your company. Once complete, open your web connector. Check the box to the left of Connex and click update selected.
