    I suspect this is your prolem:

    Microsoft OLE DB Provider for Oracle

    Don't use the MS driver. Use Oracle's driver.

    Sir Ludek,

    My Problem is:

    Visual Studio 2012,

    crystal report runtime for 2013

    oracle 11g.

    OS windows 7 64 bit.

    I am unable to connect, may be because oracle driver is not showing in the list of drivers while trying to connect.

    earlier my application was working fine with vs 2008 and OS : XP with 32 bit.

    Kindly assist.
