Context help not installed
I have an installation of Rad Studio 10.2 installed on my PC that was installed for me, when I press F1 to invoke the context help I get the following error:
'RAD Studio's help is not installed. Please Re-install RAD Studio's documentation.'
Also, when using the drop down help menu there are no options under 'Help -> Delphi Help'.
I've tried to run the installer to add the help files but the only option I have is to uninstall and re-install RAD Studio which I don't want to do.
I've also downloaded the help files and copied them to C:\Program Files (x86)\Embarcadero\Studio\19.0\Help\Doc which hasn't resolved the issue.
Is there a method to install the help files so that RAD Studio recognises them without having to reinstall the entire product?
I encountered this discussion after experiencing the same issue in Tokyo 10.2.1 - the help system apparently simply disappeared.
After a lot of googling, I found a Berlin reference to registry entry "HKEY_CURRENT_USER\Software\Embarcadero\BDS\19.0\Help\HtmlHelpFiles" (well, 18.0 for Berlin, I believe...) and checked that entry. All seemed fine.
I was about to ask for help on the ADUG list when I re-checked that key to find that "HtmlHelpFiles" had been altered to "Html1HelpFiles" (or it may have been "HtmlHelp1Files" - I forget which).
Removing the superfluous "1" restored operation.
HOW this entry got changed, IDK.
20171114T1900Z : I have created RSP-19356 to report this on JIRA.
I'm having the same problem with Tokyo 10.2.1.
I have no help files installed.
I mounted the ISO and there's exactly one EXE on the INSTALL folder: Setup.exe
I ran it again and it reinstalled a bunch of stuff, but there's still no help files.
Per the above suggestions, when I launch the IDE and the Tool menu has no "Manage Platforms" option on it.
I don't know what the "Feature installer" is. When I tried to run radstudio10_2_1_esd.exe it says it has to uninstall everything first.
When I looked in the ProgramData (install cache) folder, there are no files with 'help' in their name. Just a bunch of what appear to be compiler exe's.
This is the second time I've done a full install with no help files showing up for the core system, just what 3rd-party components loaded up.
Any other suggestions?
Have you used the "Feature installer" (blue/green-ish styled installer) or the ISO?
For the first one: Launch the IDE. Goto "Tool | Manage Platforms" and install the help.
For the second one (ISO): Modify the installation through "control panel".
