Symptoms

Installing Conferencing Manager 4.0 on a Presentation Server 4.0, with a hotfix installed, triggers the Presentation Server 4.0 installation routine.

Cause

The option “Allow inheritable permissions from the parent to propagate to this object and all child objects. Include these entries explicitly defined here” for the registry key HKLM\\Software\\Citrix\\ProductCodes is cleared by the installation of Conferencing Manager.

Resolution

WARNING! Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Make sure you back up the registry before you edit it. If you are running Windows NT, also update your Emergency Repair Disk (ERD).

Manually modify the above registry key.
