There was never a 64-bit version of the MSADORA.Oracle provider released. You will need to migrate to Oracle's own data access components instead.

64-bit Oracle Data Access Components (ODAC) for Windows[^]

thanks for answer
When I install this program does it affect the existing installed program on the host machine?

It shouldn't do, unless you already have applications using a 64-bit version of ODAC.

You'll need to install the ODAC and change the provider your connection string from MSDAORA.Oracle to OraOLEDB.Oracle.
