This is because on a TS machine permissions are locked down more than on a 
workstation.  You need to grant rights to these keys on the TS machine to 
allow that app to run.  Of course this is always a dangerous game and you 
should only give as a little as you need.  Also be aware that an app that 
is writing data to this area (HKLM) may affect all users on that app.  I 
would contact the vendor of the app and see if they support it on Terminal 
server and even potentially get them to rewrite the exe so it confirms to 
TS best practices.

Subject: [THIN] Can't write to HKey Local Machine nor Current User

Hi, 
I have a .exe and .dll installed on Windows Server 2003 for use by thin 
clients using Terminal Services. 
The thin client user logs into Lotus Notes (which is running on the 
Server) which calls the .dll which runs the .exe and passes the .exe a 
structure. 
The .exe, amongst other things, tries to read and then write several keys 
to both the HKey Local Machine and HKey Current User and this is where the 
problem lies.  The .exe only works when the thin client is given Admin 
privileges to the Server; otherwise 

Firstly, the .exe doesn't seem to find the Local Machine Keys (if not also 
the Current User keys) when the .exe loads. 

Secondly,  the .exe it exits with the following message when it tries to 
write to registry keys: 
System.UnauthorizedAccessException: Access to the registry key  is denied. 

  at Microsoft.Win32.RegistryKey.Win32Error(Int32 errorCode, String str) 
  at Microsoft.Win32.RegistryKey.SetValue(String name, Object value) 

All Thin client users have been given permission to read and write to the 
Local Machine and Current User keys. 

The .exe works on Windows machines under the same scenario (called from 
inside Lotus Notes which calls the .dll which runs the .exe etc.) whether 
the user has Admin privileges or not. 

Any ideas? 
Many thanks,
