TRichView.com

Hi, I am developing a program in Delphi on XP and I had a HD crash. After recovering the developed software, including RV packages (D7), and installing them on a new machine (also XP), keeping all software the same, the project builds and runs. However, I have a problem in design mode. Pas files that have forms with RV components on them (RichViewEdit) do not show up! Errormessage: class TRichViewEdit not found - Error creating form. Is there an easy way out of this? Thanks in advance.

1) Make sure that the packages are really installed. Do you see TRichView in the component palette?

2) Make sure that RichView packages are not included in the exclude list in your project. Open *.dpr file in Notepad and search for "exclude"

3) Search your hard drive for duplicate package files (RVPkgD7.dcp, RVPkgD7.bpl, RVDBPkgD7.dcp, RVDBPkgD7.bpl), and, if found, delete them.
Rebuild the packages and install again.

Sergey thanks. All three prerequisites are fulfilled. Now the message is: Error reading form: "Class TRVFontComboBox not found". Does this tell you more about what may be wrong? (Are there perhaps files that may NOT be in the same directory for output, search, library etc? To make sure files are found I put them all in the same directory.)

This component is included in RichViewActions, install RichViewActionsD7.dpk

Apparently there was no easy way out for me. I uninstalled Delphi and took out all of RV, then re-installed. Now it works again.

Thanks Sergey.
