    Check this: In 64 bit machines 32 bit programs are found under C:\Program files (x86)\
    -The two () parenthesis here are a problem
    In case of XP  it is  C:\Program files

    Normally you should change the location where the corrsponding applications/program are - install  on another folder.

    Do you have the 64bit Oracle provider installed?

    I add this two notes:
    1) I have not  64bit Oracle provider installed
    2) I compile solution in 32bit (x86)
    3) And the same code in a normal project works without error
