We are using Version 8.0.4.1514 of PL SQL Devleoper
(Windows 7 (64 Bit) 6.1 Build 7601 (SP1)) on a Citrix server
Windows 2008 R2 Enterprise

There are a number of instances when I get the error 'The configuration registry key could not be read' for example opening the Large Data Editor.

Does anyone have any suggestions on how to fix the install.

Thank you for your help.
