I have an Oracle client installed on my workstation. tnsping reports:
C:\temp> tnsping

However, it does not appear in Control Panel Programs. The only Oracle thing there (other than Java) is
Oracle data Provider for .NET Help
I just want to understand this (apparent) disconnect. Bingoogle found nothing (or I didn't ask the question the right way).
However, if you installed the client using "setup.exe", then - if it (or any other program you install) creates a registry key whose name is longer than 60 characters, it won't be displayed in "Programs" in Control Panel.
