TRichView.com

I installed RichView Package 13.0.1. After that I don't use this components because after using their on Form and trying to compile shows message "Unit SRVControl was compiled with a diffarent version of RichView.TCustomRichView".
I do not know what the reason.
Thanks.

Probably you have several version of components (TRichView and/or SRVControls) in different directories, and Delphi tries to compile mismatched versions.
Delete the old version and try again. Preferably use the newest version 14.5.1

Thank you. I found old *.dcu files and deleted their.
