Windows 7 How to reinstall HELP-file?

[Kari]

Hi!

I have a HP-Pavilion laptop. Windows 7 RC is running fine, having no problems. But HP´s own update tried to install HP´s own Help-file, which is no longer compatible with Windows 7. Now I have no Help! Help-window is empty, telling only "Topic not found".

Is there a way to reinstall only the Help-file?

Thanks, Kari
