microsoft odbc driver manager data source name not found and no default driver specified

Question

I am trying to run a Classic ASP application on Windows 8.1. It keeps on failing with error: data source name not found and no default driver specified

I am using an Access database. I have the same problem using a MySQL database. I tried with both 32 bit and 64 bit MySQL drivers -- first installing one then uninstalling and then installing the other.

driver={MySQL ODBC 5.3 Driver};option=3;server=localhost;user=root;password=;DATABASE=test;

I'm using these MySQL ODBC drivers:

mysql connector 5.3.4 - win32
mysql connector odbc 5.3.2 - winx64

Answer 1

Access can't be accessed through the MySQL drivers (they're for MySQL not Ms Access), what you need is the Microsoft OLEDB database connections.

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\myFolder\myAccessFile.accdb; Jet OLEDB:Database Password=MyDbPassword;

Also for MySQL, if you're running a 32bit MySQL server on a 64bit machine the standard ODBC management tool won't work since it's the 64bit version by default.

You'd need to install in on the 32bit ODBC manager here c:\Windows\SysWOW64\odbcad32.exe

Once that's done you'd need the following connection string to work with a 32bit DB on a 64bit machine. Provider=MSDASQL;Driver={MySQL ODBC 5.2 ANSI Driver};Server=localhost; Database=myDataBase;User=myUsername;Password=myPassword;Option=3;
