Problem Description:

How can I use multiple QuickBooks

Solution:

You can use multiple QuickBooks of the same region and the same version year on the same machine. But for the best configuration of QuickBooks, please get in touch with Intuit to take help.

Please note:

You may be unable to set up auto-login when you use multiple QuickBooks.

Because QODBC uses QuickBooks SDK to work with QuickBooks, QODBC /QuickBooks SDK cannot judge from the company file to determine which edition of QuickBooks to start.

The alternate solution is to keep QuickBooks running so that QODBC / QuickBooks SDK will not load new QuickBooks and can connect to existing instances.
