Error RichViewActions.pas(1293):Undeclared identifier:'TRVUnderlineType'

can you help me?

(version 10 is an old version, the latest version is 11.x)

The most probably, you have several versions of TRichView in different directories, so Delphi tries to compile some new files with some old files.
Delete files of the older versions of TRichView, RichViewActions, etc.
