In VS2010 Beta 2, from the Help Library Manager, after selecting local help, and downloading the VS Documentation, it won't launch.

Here's what I have installed:

Ideas?

I recommend reporting this bug on Microsoft Connect so that the Visual Studio product team can take a look at this.

This seems like a rather specific problem and not a general programming question.

I also had problems with VS 2010 Beta 2 help, or rather with MS Help 3, which is new with 2010 . There is a known issue with the Help Listener Service trying to listen on port 80. MS document a procedure to change this port, and my help was back up after following it. From the the ReadMe_ENG.htm file that is installed with MS Help:

1. Removal of Help 3.0 will not remove content from user's machine; they should run HLM to remove content
2. Product Documentation shortcut will not work after uninstall of Help 3.0
3. Help Library Manager requires the BITS service to be running if you want to use the “Check for Updates” or “Find Content online” features. Removing content and installing content locally does not require the BITS service.
4. Help Library Manager will hang if you attempt to install offline content but there is not sufficient disk space for the BITS service to download the content
5. If port 80 is used by another process (not via the http.sys service) then the Help listener will not be able to attach and use port 80 and will fail. The port number can be changed by adding a string registry value ListenerPort under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Help3 with the value of the port to use (eg. 81). Due to the http.sys ACL settings it is necessary to run the following http.sys configuration command from an admin elevated command line. On Vista, Win2k8, and Windows 7 run the following native command: netsh http add urlacl url=http://127.0.0.1:/help/ sddl=D:(A;;GX;;;WD)

On Windows Xp, and Win2K3 run the following command:

httpcfg set urlacl /u http://127.0.0.1:/help/ /a D:(A;;GX;;;WD)

If the command is not found then it might be necessary to download the httpcfg.exe from Microsoft as part of the Windows XP Service Pack 2 support Tools (http://www.microsoft.com/downloads/details.aspx?amp;displaylang=en&familyid=49ae8576-9bb9-4126-9761-ba8011fabf38&displaylang=en).

Now the Microsoft Help Listener will run on the selected port number.

ADDENDUM: I also ended up installing MS Help 3 manually, and using the Help->Manage Help Settings menu command. On the VS 2010 installation 'disk', I ran WCU\Help\HelpSetup.exe, after removing help via Add/Remove programs. Note the folder HelpSetup installs to, and then in VS 2010, open the Help Library Manager (Help->Manage Help Settings), then Find Content on Disk, and then supply the location HelpSetup installed to. Help 3 will take it from there.
