ParentOriginalDatabase property

During a concurrent installation, the installer sets the ParentOriginalDatabase property in the concurrent installation's session to the same value as the OriginalDatabase property in the parent installation's session. Parent installations use the concurrent installation actions to perform a concurrent installation. An installation package can determine whether it is being installed by a concurrent installation action by checking the value of this property.

Note  Concurrent installations are not recommended for the installation of applications intended for release to the public. For information about concurrent installations please see Concurrent Installations.

Note  This property is not set if the concurrent installation is being run by the RemoveExistingProducts action.

Remarks

To prevent a package from ever being installed as a concurrent installation, add either of the following conditional statements to the LaunchCondition table. This prevents the package from ever being installed by a concurrent installation action run by another installation. This does not prevent the package from being installed by the RemoveExistingProducts action.

"Not ParentProductCode"
"Not ParentOriginalDatabase"
