The other steps are similar to the installation server side.

B. PL/SQL Developer installation Note:

before you install PL/SQL, you need to install the Oracle client first.

My system environment:
1, 64-bit Windows 7 Ultimate Edition
2, 64-bit Oracle 11g R2 DB
3, 32-bit Oracle 11g client (64-bit Oracle 11g client error)
4, PL/SQL Development 8.0.4

Attention:
(1) PL/SQL development do not install in the default C:\Program Files (x86) directory, otherwise you will get an error, because the path of this band () cannot be resolved.
(2) When the Oracle client installs a 64-bit Oracle 11g client, starting PL/SQL developer will prompt for errors.
Cause: Oci.dll is a 64-bit, 32-bit application PL/SQL developer cannot be loaded and can be fixed by installing a 32-bit Oracle client.
