Check the value of the tns_admin system variable. To do this:
Open a command prompt, and type “set tns_admin”. You should see the following path returned: c:\oracle\product\<some version>\client_1\network\admin. If not this value, then you will need to set the environment variable to your actual path name.
Look at the c;\oracle\product\<version> folder. You should just have a client_1 folder at this level, but I’m guessing that you may also have a client_64 folder, which means that Oracle 64 is also installed. If so:
Go into your system environment variables, and check your PATH variable. The client_64 path will likely be before the client_1 path in the string of paths. You need to move the client_1 entry to be the first entry in the PATH variable.
You will also need to update directory and file permissions so that the folders and files under the client_1 path have read/write opene dup opened up on them. The Oracle 64 install changes permissions on the client_1 folder and everything below, closing them off.
