Online said to go to Oracle's official website to download a corresponding but Oracle official website need to register too much trouble
Did not fix a lap (Sqldevelper and download and configuration or a variety of errors finally gave up)
Finally, you can only go to Oracle register to download OracleClient
Since my version of OracleClient and the Oracle version on our server are all 10
So, also from the official online 10_2 and is 64bit
HTTP://PAN.BAIDU.COM/S/1JIIFCSM I downloaded the address on my web drive.
After downloading, the extracted instantclient_10_2 replaced the original folder with the same name (early backup)

Then exit Navicat reopen
Just try it again.
