Install on Terminal Server

Firstly install the software,from the above download, to the local drive of the RDC server using the instructions above. All users must be able to see this folder


  • This Location must be visible to ALL users
  • Each user must have FULL access rights to the folder you have designated to install the software.

This will install the software on current PC only.  Now to add to all Terminal Server sessions you need to put the server in install mode and then run ClientInstall.exe from the network directory you have installed the software into.  You can use UnInstallClient.EXE to uninstall if need be later.

Publish to other users

While logged in a Admin user, on terminal server we publish the Simply Postcode Desktop app to other users using the following:

Open a command prompt

Navigate to installed directory, where Simply Postcode is installed, and enter:

   Comand Prompt

c:\windows\system32\change user /install


c:\windows\system32\change user /execute

Instead of navigating to the folder, you could enter:

   Comand Prompt

c:\windows\system32\change user /install


c:\windows\system32\change user /execute

If long folder names have been used with spaces in them you would need to wrap the ClientInstall.EXE statement in Quotes.

IGNORE ANY errors when installing.

Start when user logs in

Normally the client install will add a shortcut to start "lookup.exe" when the PC starts. Terminal server does not allow this so we need to use Task Scheduler to start lookup.exe when the user logs in.

So from the Terminal Server, Server Manager, start "Task Scheduler" from the "Tools" menu.

Next create a new task, but selecting "Action >> Create Task"

Enter a name and "Run only when user is logged on"

Add an action to start the "Lookup.exe" in the directory you have installed Simply Postcode in:

Select "Run a new instance in Parallel":

You should have now finished the install. Simply log in as a user to test.
