We are using PL SQL Devleoper version 7.1.4 and published on a Citrix server Windows 2008 R2

Enterprise.

When I am trying to access the CLOB values, we are getting following two errors in sequence for only

few users.

1. The configuration registry key could not be read

2. Access violation at address 0042894E in module 'plsqldev.exe'. Read of address 00000000

However, we are not getting the similar error for other users who is login in the same server. I am wondering, how it is working for few users and not working for others.

Can you provide solution please
