We have not been able to reproduce this. It works just fine on Windows Vista. If you have any additional information that could help use reproduce this, let me know.

Did you work as a normal user and have UAC enabled?

Yes. Are you using the final Vista version or a Beta/RC?

Furthermore:

1. Did you install the Oracle Client as Administrator or as a Normal user?
2. Did you install the PL/SQL Developer as Administrator or as a Normal user?

1. I use the final german "Ultimate" Version from our MSDN account.
2. I was logged in as normal user and run the setups as Administrator.

That's exactly the same as my setup (except for the German lamguage). Were both Oracle and PL/SQL Developer installed as Administrator?

In my case too, so we have the exact same setup.

To obtain some more diagnostic information, can you modify the shortcut and add the debug parameter? For example:

"C:\Program Files\PLSQL Developer\plsqldev.exe" debug

Reproduce the problem and send me the debug.txt file that is generated in the PL/SQL Developer directory.

Hi,

I have exactly the same problem using the latest versions of the Oracle client and PLSQL Developer.

I installed (twice, uninstalling first and removing directories) them as Administrator on Vista Ultimate.

The debug.txt file is simply not produced when I try the above. All I get is a little box with no text and an 'Ok' button, which takes me back the logon prompt for PLSQL Developer.

Interestingly enough when installing Oracle client, in the test the connection bit, it says the connection works.

Is this really not a problem for other people?

You are not the only one with this problem, as indicated by this thread.

About the missing debug.txt file: can you check if you have write access to the PL/SQL Developer installation directory? If you do not have write access, log on as admin and grant write access, log on as a normal user, and try the debug option again.

Can you also check if <OracleHome>\Bin is listed in the PATH environment variable?
