Enterprise Trial Edition RegOpenKeyEx Problem

[Mark Jacobs]

I have just installed the trial version of the Enterprise edition of VNC 
4.13

I installed the server on about 15 PCs and on most of them I got this 
message during install :-

RegOpenKeyEx (open): The system cannot find the file specified. (2)

Continuing the install seemed to be successful, and it generated the 
necessary keys.

When I try to view these particular stations with VNC Viewer 4.13, I get 
this message :-

RegOpenKeyEx (open): The system cannot find the file specified. (2)
Do you wish to attempt to reconnect to ww.xx.yy.zz?
        YES       NO

If I say Yes, it comes back almost immediately with the same message. If 
I say No, the viewer exits immediately. What have I done wrong?
