Multiple Windows Installer (.msi) Packages Cannot Write to the Same Registry Key on a Server That Is Running Terminal Services

If you are installing multiple Windows Installer packages on a server that is running Terminal Services, the second package may not correctly update the a registry key. This problem may occur if:
  • You do not restart the server between the installations.
  • Both packages try to write to the same registry key.
When this problem occurs, the second package does not correctly update the same registry key as the first package, even if the values are different.
The Terminal Services Install mode incorrectly propagates the modified key.
