Why can't Multi-Edit find WebLair Help?
There are two help files that could be at issue here: the Multi-Edit user help file <ME_PATH>\Help\ME.chm, which contains help for some of the WebLair configuration dialogs; and the HTML reference file <ME_PATH>\Help\HtmlRef.chm, which contains the bulk of the HTML-related help, including context-sensitive help.
The most common cause for this problem is that you didn't allow Multi-Edit to fully install at some point in the installation. To verify that the help is set up correctly,
- Verify that the two help files actually exist, and that you have adequate access permissions to read them.
- From the main menu, select Help | Manage Help Path and Files... to open the Manage Help Files dialog.
- Verify that Multi-Edit Help is listed, that it's assigned to the global variable !ME_Hlp, and that it's set to <ME_PATH>\Help\ME.chm, for whatever path <ME_PATH> happens to be in your installation ("<ME_PATH>" should not literally appear).
- Verify that HTML Help File is listed, that it's assigned to the global variable !WL_HtmlHelp, and that it's set to <ME_PATH>\Help\HtmlRef.chm.
- And finally, verify that Master Help Path is listed, that it's assigned to the global variable !HelpPath!, and that it's set to (by default) <~!Delphi_HP>;<~!BCpp_HP>;<~!WCpp_HP>;<~!Inf_HP>.
Note that the Master Help Path consists of other global help variables in a semi-colon delimited list. You can add any of the already-defined globals to this list, or define new ones and add them. This variable allows help files to function globally, instead of in a context-sensitive manner.
Should nothing be amiss in the Manage Help Files dialog, check out No Viewer for MEW Help, which gives instructions on how to verify that the viewers necessary to read various kinds of help are present and installed correctly.
If none of this helps, and all OS user permissions are set correctly, I would suspect a corrupt installation. Should you decide to uninstall and reinstall clean, be sure to make a complete backup of Multi-Edit first, to ensure you still have a backup copy that contains your customized settings. If this copy is accessible when you install the new copy, you can point the installer to its location, so that it can copy your configuration settings (except for things like template files, which you'll have to copy by hand).
