TRichView.com

Hi Sergey,

I do not think it is just a simple 'may' but instead Delphi would show a definite error especially if old properties/functions/medhods have been added or removed

Regards.

This error message occurs not on old updates, but only if old installed addons (RichViewActions, RVHtml, etc.) cannot be compiled with new version of TRichView. So, when you update TRichView package, others cannot be installed until you update them too.

It happen if some TRichView's internal methods or properties (used by addons) were removed or their parameters were changed. It also happens, as far as I remember, when new values are added to enumeration types.
