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,
