. I try to connect my BI project in visual studio 2008 to mysql database. so I defined odbc connection in Start > Programs > Administrative Tools > Data Sources [win 7] and I tasted it, it connected successfully .
but when I want to open this connection in VS > “View” > “Server Explorer”, I see this error:
ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN
contains anarchitecture mismatch between the Driver and Application

even I put “root” as user name in the text box and pass empty [bc I didn`t set pass for my mysql db] , but nothing changed!!

If you use the 64-bit odbcad32.exe to configure or remove a DSN that connects to a 32-bit driver, for example, Driver do Microsoft Access (*.mdb), you will receive the following error message:
The specified DSN contains an architecture mismatch between the Driver and Application
To resolve this error, use the 32-bit odbcad32.exe to configure or remove the DSN.
