Hello
I get this error message: Cannot load Oracle client. Check your PATH environment variable and registry settings 
But i don't know what exactly I should check there ?

From the windows interface, first verify your ORACLE_HOME in the environment path in My Computer —> settings —> advanced settings.  The path should be in the first 128 chars of the path and the correct one should be displayed clearly.  Once you see this path, verify it’s correct and no other oracle installation has priority.  In the registry, you can go to the HIKEY\LOCAL_MACHINE\SOFTWARE\ORACLE, check if there’s more than one home entry and verify the entry for the client home.
