1) Powerdesigner needs to be cracked, the cracked file is easy to find (omitted)
2) The default connect database in the powerdesigner menu is the called 32-bit odbc. It is called C:\Windows\SysWOW64\odbcad32.exe. Before opening C:\Windows\System32\odbcad32.exe, the test connection has been no problem, but the connection in powerdesigner will report the following error
3) The oracle client does not need to be downloaded. You can download the oracle instant client 32 bit. Both basic and odbc versions need to be downloaded from http://www.oracle.com/technetwork/topics/winsoft-085727.html
