IIS7 application errors with providex odbc driver

I have a Windows 2008 SBS x64.
Setting up in IIS7 an asp.net application in the default website.
My application access a providex data source with the providex 32bit odbc driver.
I set up the driver with the c:\Windows\SysWOW64\odbcad32.exe
I have tired using the default application pool and also created a new application pool set to run in 32bit.
I also set file permissions to everyone full control.
I also gave the nt authority access to the dot net framework directory and iis metabase via command C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -ga "NT AUTHORITY\NETWORK SERVICE

The strange thing is my application runs fine on Windows server 2008 standard. I cannot find the differences in my configuration between the two OS.

Here are two error message. One with 32bit and other with 64bit application pool

 Most likely causes:
•The worker process is unable to read the applicationhost.config or web.config file.
•There is malformed XML in the applicationhost.config or web.config file.
•The server cannot access the applicationhost.config or web.config file because of incorrect NTFS permissions.
 Things you can try:
•Look in the event logs for information about why the configuration files are not readable.
•Make sure the user identity specified for the application pool, or the authenticated user, has the required permissions to access the web.config file.
 Links and More InformationThis error occurs when there is a problem reading the configuration file for the Web server or Web application. In some cases, the event logs may contain more information about what caused this error.
