MSI does not support "Install if present" here

The installation action Install if present is not supported by MSI. To work around this limitation, InstallMate replaces this action by Overwrite existing value. However, this might not always be appropriate.


MSI only supports a subset of the generally available installation and removal actions offered by InstallMate. Moreover, the available MSI subset depends on the object type.


If Overwrite existing value is an acceptable substitute, you can ignore this message. Otherwise, select a different installation action for the object. Use the See also section below to check which MSI installation actions are available for each object type. Alternatively, build an InstallMate installer instead.
