Installation Notes

Installing this update uninstalls the current help and then installs and registers the newest Help Update.

Requirements

This Help Update can be applied to:

• CodeGear RAD Studio 2007
• C++Builder 2007 Update 3
• Delphi 2007 for Win32 Update 3

Important: This Help Update cannot be applied to prior software versions. You must update RAD Studio to one of the versions listed above to be able to use the Help Update mechanism.

Help Update History

Installing the Help Update from the Registered Users Site

You can obtain the help update download from the Registered Users Site. Install Help Updates using this command:

   HelpSetup /upgrade

Known Problems with the Help Update Installer

• If you close the Update before the install completes, when you run Check Update again, a message says there is no Update available. The workaround is to download and run HelpSetup /upgrade from the Registered Users Site.
• If you have registered 3rd party help in the RAD Studio/5.0/Help/Doc/h2reg.ini file, you may have problems if you used syntax that is not compatible with RAD Studio Help. See How to Plug 3rd-Party Help into RAD Studio Help for instructions.

Improving Install Performance

1. DisableRollback

   The MSI-based Delphi installer uses a transactional database to keep track of its actions. This feature enables you to cancel and "rollback" the installation process, which means you can backtrack the install actions performed up to that point.

   You can disable the rollback support by setting the following entry:

   Windows Registry Editor Version 5.00
   [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer]
   "DisableRollback"=dword:00000001

   You can also use the same setting under HKCU, which will be applied in a per-user basis.

   Notice that this setting will affect *all* MSI-based installs, not only the help install.

   Turn the registry setting back after you are done. Either delete the registry entry or set the value to 0.

2. DisableAutomaticApplicationShutdown (Vista Only)

   This registry entry setting disables the Restart Manager, which tracks files in use during an install process. (On Vista-based install, this can cause long delays.)

   For the following registry entry:

   HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Installer

   Set a DWORD value named DisableAutomaticApplicationShutdown to 1.
