QODBC License Details FAQ:

Question:

Would you be kind enough to give me any information that you have that would enable me to get the application to run and all of the machines in the network? I have the server edition, and I have tried using the DCOM setup procedure without success. Can you indicate to me how to set up the DCOM?

Answer:

Please refer below article for how to set up the DCOM server:
How to setup QODBC DCOM Server

I want to suggest you use QRemote instead of the DCOM server. Please refer to the articles mentioned for QRemote configuration.
Accessing QuickBooks Data Remotely using QODBC & QRemote

I guess you might be trying to configure QODBC -DCom so that other machines can connect to your server machine having QODBC + QuickBooks.
I want to share that QODBC is not a client-server application. To access data from the remote machine, you need to use QRemote. Install QODBC on the client machine and, using the QRemote client, connect to your server, which runs QRemote Server.
QODBC Server edition license is required when you have any service-based application like SQL Server, WebServer, or Windows Service connecting to QODBC and not when a remote machine connects to the machine.

Question:

I purchased the server edition with the expectation that it could be used in a multi-user environment. Currently, my client has eight workstations that are linked to a server in the network. I wanted to find out if the DCOM feature could be used, and you recommended using QRemote. However, the literature he recommends that I use suggests that QODBC should be loaded on each workstation. My query is, can't the server edition work, or do I have to purchase a driver for each workstation? Please explain.

Answer:

The server version of QODBC is not a driver you would install on a server, and multiple workstations would have access to it. QODBC is a client-side driver that would typically reside on the workstations. The server version of QODBC is for synchronizing SQL Server with QuickBooks data or for a web or intranet application. It is multi-threaded and can run as a service.

Question:

I have a developer doing most of the development work on his desktop computer. I have to test and verify his work on my personal desktop computer. I have a separate desktop machine where I run the software for my small business. Everything for the company is done on that one machine. I would need to purchase two licenses at 149 each since the license is per user, even though I need to run the software on two machines. Could you please confirm?

Answer:

You must purchase two licenses if you want to work with live data on both machines. You can continue with one license if your developer works with a sample business file. For working with a sample file no need for licensing. Your developer can work with sample files without licenses, and You can test his work on your machine with licenses.
