Embarcadero RAD Studio XE3 Update 2 , Help Update 3
Vinnie Breidenthal
Open a command prompt, and navigate to your $(BDS)\Help\Doc folder. Run H2Reg -u to unregister the existing help topics, and then run H2Reg -r to re-register. THen launch help, and you should get the dialog that says it's indexing content.
2 - Antoher reason is that you can have a corrupted help (it happens when you install some fixes from microsoft as the windows 7 sp1 for example). The only way in this case is to reinstall the help (check it out Delphi).
I experienced the same problem, but the H2Reg fix never worked for me. :( I tried running Delphi RAD Studio XE2 as Administrator, even though my user account was already set to Administrator, and tested F1 including the context help. Everything worked as expected :) Afterwards, I closed Delphi, switched off the Run as Administrator option, reopened Delphi, and the help worked perfectly. :)
The methods of using h2reg.exe did not work for my case (RAD Studio XE3).It costs me several hours to find out my solution.The root cause of my problem is the broken Microsoft Document Explorer 2008.I try to repair it from Control Panel -> Uninstall Application.Surely you can remove it and install it back from many source, including the help system of RAD studio.

Generally try to clarify description adding more details and/or context info using the recommendations given above or add/review steps to reproduce. Attaching screenshots and/or projects would be helpful as well. A short and focused video can also be good to understand.

Strange. I got an email with your response to my comment, but I don't see it here. Anyway...
"Marjan, I do know a thing or two about working with delphi runtime & component packages.. been doing it for a long time. Of course we build third party libraries and components from source. Do you seriously (on your dev machine) have a copy of everything in the output folder of every project? Having more than one copy of rtl160.bpl etc on your machine is just asking for trouble (dll hell). "
Of course you do, that's why I was surprised...
No, I don't ... because we don't build with packages. However, if we did, yes I probably would.
I like it when I can press a single button, or run a single script and be absolutely for sure that any app I subsequently start is using _only and exactly_ what I just built and so is completely unaffected by whatever else have on my (dev) machine.
Having multiple copies of a single dll is not what is known as "dll hell".
Dll hell is when you put all dll's in a single folder (such as windows\system) and give all versions of a dll the exact same name. That way you can't have multiple applications dependent on the different versions of a dll. Upgrading one of the applications can then break another when it installs a newer version of that dll.
Since Delphi supported versioning in the name of the build target, that problem has gone and you can indeed put all packages in a single folder. But when you do, your application - and/or your dev environment - becomes dependent on the environment's path. And your application can stop working because somebody else (like Embarcadero) was less than civil when amending the path to suit their needs.
I don't much like trouble shooting these kinds of problems and while I probably wouldn't suffer them (or easily solve them) on my own development machine, I prefer to have a development environment that is as close as possible to the "real" installation at one of our customers. In fact our source control is set up to include a folder that exactly mimics our application's folder as it would be after a clean installation on a customer's machine. It helps to avoid a lot of those "it works on my machine" situations.
Also, having everything together for every version / branch on my dev machine gives me the freedom to use a single name or use versioned names for dll's or packages. And I like my freedom .
Oh, and you don't have to change the system path when you install your application (as Embarcadero shouldn't do either). Just put a cmd file along side your application in your application's root folder and put all dll's in a bin sub folder. Start your app through the cmd file and set the path in there before you start your exe. That way you can always have a "clean" path regardless of what the environment's path is. Of course all your application's shortcuts should point to the cmd file instead of the exe.
Scott, if you use runtime packages you do need those entries on the path (for third party packages).
Taz, I used to do that, but the length limit applies to the expanded value so it doesn't work.
KM, I tried that, on my windows 7 x64 machine, if I open a cmd window, and type set, the path shows as truncated. I also had all sorts of problems with my machine because of the path truncation. I could not find a difinitive answer on the microsoft site, some pages say env variable can be 2047 chars, some say 1024. I've had this problem several times over the last few years, each time after installing a new version of rad studio.
Building on the importance of Visual SQL Tuning tools, the latest version of DB Optimizer introduces query tuning reports, to improve collaboration between DBAs and developers and help to cut down on the time spent tuning, says Walz. With XE3, DB Optimizer is also introducing key profiling updates, such as enhanced filtering for profiling sessions, and improved repository management when capturing profiles into a database.
And this can be really helpful: When you want to step in the FlexCel source code with F7, and you want exceptions to break in FlexCel code, you set "Use debug .dcus" to true in your project options. When you want to focus on your code and see FlexCel as a black box, set "Use debug .dcus" to false.
