When you install PL/SQL on 64-bit win7, you often encounter "Could not load". \ bin\ oci.dll "" this error, I checked the information. The reason is that PL/SQL only supports 32-bit OS. The solution is to load an additional oci.dll file, as follows:

Step1:

Download the package "instantclient_10_2" containing oci.dll at the following address, and extract the file to "D:\ Program Files\"
