Problems with ODBC 5.2 64bit
Posted by: Sandeep Chadha

I have a server where I have installed ODBC 5.2 64 bit driver. As I understand this installs both 64bit and 32bit drivers. I have even verified this by looking into the system32 and syswow64 folders and both have their own odbc32.dll.

Now when I use this in Windows 8 server IIS8, all sites work correctly while in 64bit. Now there is a site that needs to consume a 32bit dll and for this I enable 32 bit applications from the app pool for that site, and doing this the ODBC connection fails.

Now I need to know why is it happening when there is a odbc32.dll present in the syswow64 folder. Also when I use odbcad32.exe to see the installed drivers, I dont see the mysql drivers for 32 bit here.

I get the following error:
Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

My connection string is as follows:
Provider=MSDASQL;Driver={MySQL ODBC 5.2 ANSI Driver};Server=localhost;

Please help me as this is very urgent.
