Help is also not working for me. The previous reply "Environment->Options->Help->Help Options: " does not seem applicable. Under Environment/Options I see only Environment, Editor, CodeTools, and Debugger. None of those have a Help entry when expanded. There is a Help button at the bottom of the form, which is not active, I suppose because Help has not been configured.
Under the Help menu item there is a "Configure Help" option which has tabs General, Viewers, and DataBases. Under General I guessed that "C;\Lazurus\Docs\Html" is the correct entry. Under Viewers i have no idea what to enter. I use IE8 as web browser, is that my Help viewer?
Under DataBases there some of the help database file names with properties for each like "Autoreg, BaseURL, KeywordPrefix, Name, and Tag. Autoreg is set to "False" for and others are blank.
Stupid animated icons at the top of this page won't let me scroll down to finish this message! Help!
