Failed to set data, when installing help files 1

[sggaunt]

Anyone know about this?

When attempting to install help files for a third party component, I get 'Failed to set data for CPort.hlp' same for toc file.

FWIW in searching I find that a message like this occurs because a registry key fails in getting set. Keep in mind that hlp went the way of the dinosaur in Windows Vista and Seven, so you might have issues there if you are trying this on those OSes.

Hopefully that's some clue towards the answer you seek.

It is not possible for anyone to acknowledge truth when their salary depends on them not doing it.

Yes it is a Vista System, what is annoying is that all the installed by default 3rd party components e.g Indy, TChart the help system works fine.

This is a common mistake in the creation of the registry component. Traditionally, most people are used to...

var
  R: TRegistry;
begin
  R:= TRegistry.Create;

But like mentioned above, it will not work with later version of Windows. Instead, you have to tell it how you will be accessing the registry:

var
  R: TRegistry;
begin
  R:= TRegistry.Create(KEY_READ or KEY_WRITE)

You would set this accordingly depending on how you intend to access the registry. This is because of new security features in Vista and above.
