Help, Cannot connect to ODBC database using SQL Toolkit!

Question

Hello All,
I am toying around with the SQL Toolkit evaluation (2.2 + the patch) and I am having difficulty.
I ran the example program "connect" and it seems to work fine.
However, I try to write my own program and I keep getting the same message:
"Function DBConnect: (return value == -10 [0xFFFFFFF6]).
Native error code - 2147467259 0x80004005
The message differs from time to time, but the return value is constant.
I am using both Microsoft SQL Server 2012 and MySQL.
For MySQL I have installed the latest ODBC connector, 5.3.4. Inside the Control Panel/Data Sources(ODBC), I have a DSN named test_mysql in both User DSN and System DSN.
I ran a test on the connection and the test passes. I am not sure if I should use the ansi or unicode driver, I have tried both with the same success.
I am not sure I had configured the SQL Server connection properly, and will attempt that again.
My CVI Code is simple enough:
hdbc = DBConnect ("DSN=test_mysql"); 
Every time I get a -10 from DBConnect. Either I have something configured wrong or I am missing something.
Does anyone have any suggestions?

Update 2:
After getting off the phone with Tech Support the problem has been identified!
LabWindows SQL toolkit requires 32 bit DNS. My PC is a 64 bit, so my DNS manager defaulted to 64 bit.
I needed to use the 32 bit DNS manager when working with the toolkit.
Once I created my DNS connections using the 32-bit version of the ODBC Datga Source manager, everything worked fine.
