So, seeing I can't get TlzRichEdit to install....
Putting aside WP's version of LzRichEdit, the official repo has not been updated for five years. Maybe you need to think about an alternative ? I'd suggest its TRichMemo and TKMemo. As you note, TK has announced he is no longer interested in developing KControls (which includes KMemo) but will 'manage' it in an ongoing mode. Its functional and works across Linux, Mac and Windows. Its big and pretty complicated. As you found, supported in Onlinepackage manager.
On the other hand RichMemo is a lot smaller and also available in Onlinepackage manager. Its sort of complete in Linux and windows, lots missing on the Mac. My recent experience is its a lot easier to get things fixed in KControls than Richmemo but, obviously, the future is not as clear. I have made wiki pages about both,
http://wiki.freepascal.org/KControls/KmemoNotes and
http://wiki.freepascal.org/RichMemo/WorkArounds.
In light of TK's announcement, I recently reviewed my decision to use KMemo rather than RichMemo. I decided to stick with KControls because of its Mac support and its completeness. I'd prefer RichMemo's lightness but several reports and suggestions went unanswered.
(If you are pasting images, use fixes_2_0 rather than Laz 2.0.0, there is a Linux bug ....)
