Troubleshooting - app_already_purchased error when trying to Authorize QODBC in QuickBooks Online

Problem Description:

We have some other users of QuickBooks online for the same company file. And when any other user tries to authorize and connect it through QODBC, it gives the error as shown below:  

Please help me to resolve this error.

Solutions:

You are getting this error because another user (i.e., shown in the error message) has already subscribed to QODBC & Intuit is not allowing multiple subscriptions for the same company file. So it would be best if you disconnected the QODBC subscription from QuickBooks Online by logging in with the user's credentials ( the user shown in the error message).

Please follow the below steps & share the outcome:

1) Login to https://qbo.intuit.com/ using with user's (user which is shown in the error message) credentials.

2) Click on Apps from the menu.

3) Navigate the My Apps tab & you will find QODBC For the QuickBooks Online application.

Please click on the Disconnect button, 

It will ask for confirmation. Please click on "Next" by clicking on "Next," QODBC Online will be disconnected from your company file.

4) Please authorize QODBC with the user you want to connect. Please refer:
