Context sensitive help on compiler messages no longer works in Delphi Seattle

Question

I have just installed Delphi Seattle Upgrade 1.

f1 or ctrlf1 no longer work when I'm on a compiler warning/error.
I just get No help found for DCC32.

This used to work in my previous XE2 version.

Anything I can/should do to fix this?

Note added: all 'regular' help from within the editor works fine; including 3rd party documentation.

Fwiw, I get the same "No help found..." message in Seattle Update 1, so it's not just you. — MartynA, Apr 21 '16 at 08:05
FWIW, what happened with help in XE2 is irrelevant, since current versions use a totally redesigned (reverted to CHM) help system, and therefore are not even the same beast. — Ken White, Apr 21 '16 at 12:37

The most likely cause is a mismatch in the registry keys.
This happens if you install Seattle in one directory, do an uninstall and then reinstall in another directory.

The solution is to fixup the registry entries for the help.

Go to HKEY_CURRENT_USER\Software\Embarcadero\BDS\17.0\Help\HtmlHelp1Files
and manually fix the paths.
I've included a copy/paste from my system.

Note that the \\ are only in the .reg file. In regedit you'll only see a single \.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Embarcadero\BDS\17.0\Help\HtmlHelp1Files]
"Dinkumware Help"="C:\\borland\\delphi10\\help\\Doc\\dinkumware.chm"
"IDE Code Examples Help"="C:\\borland\\delphi10\\help\\Doc\\codeexamples.chm"
"IDE Data Help"="C:\\borland\\delphi10\\help\\Doc\\data.chm"

"Indy Help"="C:\\borland\\delphi10\\help\\Doc\\Indy10.chm"
"TeeChart Help"="C:\\borland\\delphi10\\help\\Doc\\teechart.chm"
"Jcl"="C:\\Users\\Johan\\Documents\\Embarcadero\\Studio\\17.0\\CatalogRepository\\JEDICodeLibraryJCL-2.8\\help\\Jcl.chm"
"JclContainers"="C:\\Users\\Johan\\Documents\\Embarcadero\\Studio\\17.0\\CatalogRepository\\JEDICodeLibraryJCL-2.8\\help\\JclContainers.chm"
"JclDeveloperTools"="C:\\Users\\Johan\\Documents\\Embarcadero\\Studio\\17.0\\CatalogRepository\\JEDICodeLibraryJCL-2.8\\help\\JclDeveloperTools.chm"
"JclVcl"="C:\\Users\\Johan\\Documents\\Embarcadero\\Studio\\17.0\\CatalogRepository\\JEDICodeLibraryJCL-2.8\\help\\JclVcl.chm"
"VirtualTreeview"="C:\\Users\\Johan\\Documents\\Embarcadero\\Studio\\17.0\\CatalogRepository\\VirtualTreeView-5.5\\Help\\VirtualTreeview.chm"
"Win32"="C:\\borland\\delphi10\\help\\Doc\\Win32.chm"

Once all the paths match the actual locations of the help files, F1 should work again.

Smart suggestion, but it did not help. I *did* uninstall and reinstall, but all to default paths. All these registry paths point to existing files, with the exception of a missing teechart.chm. — Jan Doggen, Apr 21 '16 at 12:37
