The first step is to remove all the FLEXquarters QODBC Intregated Applications in your QuickBooks company file. To do this you must start QuickBooks as the Administrator. Go to the "Edit-Preferences" menu item in QuickBooks. Then select the "Integrated Applications" icon from the left side.

Then rename C:\WINDOWS\system32\I9K4UQLW.ocx to C:\WINDOWS\system32\I9K4UQLW.bad then reinstall QODBC v9 (you might need to reboot) and you should be back to a 30 day evaluation.

From there see: How does the 30 day evaluation work? How can I evaluate the Desktop Edition? 

It reads:

QODBC Driver for QuickBooks

QODBC Desktop Read Only 2008
Version 9.00.00.253

Trying using qbcust.asp and give full read and write rights to C:\Program Files\QODBC Driver for QuickBooks\ to the Anonymous web user IUSR_machinename, ASPNET user and INTERACTIVE. This allows access to the DCOM server executables.

See: How can I see QuickBooks data in a Internet Explorer Browser using Windows XP? 

I confirmed that I did give full read/write rights to C:\Program Files\QODBC Driver for QuickBooks\ to the Anonymous web user IUSR_machinename, ASPNET user and INTERACTIVE. I ran qbcust.asp and got the following:

QODBC Customer Web List Demo Page
Preparing to Create Connection Object
ADO Connection Created
ADO Recordset Created - Opening QuickBooks Sample Company File

It never did get any farther than this.

One other note - I did read the posting "How can I see QuickBooks data in a Internet Explorer Browser using Windows XP?" and found the one step I could not do was "Uncheck the "Allow IIS to control password" setting for Anonymous access in IIS as shown here and set your own password." This checkbox doesn't appear on a Windows Server 2003. What is the significance of performing this step?

Yes, I've rebooted the server. And just for the heck of it, I rebooted it again lastnight but qbcust.asp still hangs today. Here are a couple of observations I've made:

• The VB Demo works fine. When running the VB Demo, I notice QBXMLR2eQODBCInteractive appear in the list of Processes in the Windows Task Manager running under the account that I am logged in as on the server which is Administrator. I also notice activity being written to the QODBC Messages log as well as the Trace log. And I notice the QODBC driver icon in the task tray showing activity along with the verbose messages informing me of what the QODBC driver is doing.
• When trying to run qbcust.asp, QBXMLR2eQODBCInteractive also appears in the list of Processes in the Windows Task Manager but running under the IUSR_MachineName account. However, there is no activity being written to the QODBC Messages log nor the Trace log. Note that I did give read/write permissions to the IUSR_MachineName, Interactive, and ASPNET accounts to the folder where the logs are stored. The QODBC driver shows no sign of activity.

So while IIS successfully launches the QBXMLR2eQODBCInteractive DCOM object, it doesn't appear to get the QODBC driver to do anything. Any ideas on where it is getting stuck at?

Everytime I launch QuickBooks, I do get that warning about IE's security settings being too high. For security's sake, I always decline to have QuickBooks lower IE's security settings. I do leave QuickBooks running, though, while performing tests on QODBC. I don't think IE's security settings is causing the problem since I am able to perform queries just fine via the VB Demo.

For the sake of the augument lower it and try qbcust.asp again.
