MSI does not support "Remove key and values" here
MSI does not support the installation or removal action Remove key and values for registry keys. To work around this limitation, InstallMate replaces this action by Create on demand if used as an installation action, and Remove if empty if used as removal action. 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 the indicated replacement actions are acceptable substitutes, you can ignore this message. Otherwise, select a different installation or removal action; see Registry keys to check which actions are supported by MSI. Alternatively, build an InstallMate installer instead.
