MSI only supports "Append/Prepend to existing value" for REG_MULTI_SZ

The installation actions Append to existing value and Prepend to existing value are only supported for REG_MULTI_SZ registry values by MSI. To work around this limitation, InstallMate replaces this action by Overwrite existing value for other registry value types. However, this might not always be appropriate.

Background

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.

Solution

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.
