System.Data.OracleClient requires Oracle client software version 8.1.7 or greater

Errorinfo is "System.Data.OracleClient requires Oracle client software version 8.1.7 or greater."

I have installed Oracle Client 11g (11.2.0.1.0) on Server is greater than 8.1.7 , still the error comes. On serching out I find out following solution:

It is a security issue, so to fix it simply do the following:
1- Go to the Oracle Client folder.
2- Right Click on the folder.
3- On security Tab, Add "Authenticated Users" and give this account Read & Execute permission.
4- Apply this security for all folders, Subfolders and Files (IMPORTANT).
5- Don't Forget to REBOOT your Machine; if you forgot to do this you will still face the same problem unless you restart your machine.
