An error in RvHtmlViewImporter

[saeid2016]

Hello,
I installed the RvHtmlViewImporter on Delphi Tokyo. When I run the project it gives this error:
[dcc32 Error] rvHtmlViewImport.pas(191): E2037 Declaration of 'LoadFromClipboard' differs from previous declaration

Maybe you have an old version of RvHtmlViewImporter files in a folder available for this project, so the project is compiled with a wrong version of RvHtmlViewImporter?
Search for duplicate rvHtmlViewImport.pas files.
