以下是Microsoft Help Viewer Power Tool (Beta)的安装说明：
1.If Help Viewer Power Tool is installed while Help Library Agent is running, the installation of the Help Viewer Power Tool will spawn another instance of the Help Library Agent, and two icons will appear in the system tray. Closing the first instance will cause F1 to fail for the given session.
Work-around: Make sure that Help is closed and the Help Library Agent is not in the system tray before installing Help Viewer Power Tool
2.Help Viewer Power Tool setup does not work for non en-us Visual Studio 2010 versions.
Work-around for installing Help Viewer Power Tool for a localized (VS\100\) catalog, and before installing the Help Viewer Power Tool (note that the below uses ja-jp as an example locale, and that while the work-around should support localized content, the UI will still be in English):
1.Go to your manifest folder under the help local store folder .
2.Open QueryManifest.*.xml file for edit
3.Look for the following entry: catalog productId="VS" productVersion="100" productLocale="JA-JP." If this string is not present, then edit one of the existing catalogs to this value. For example, if you have VS\100\JA-JP locale installed, you will have the following entry:
catalog productId="VS" productVersion="100" productLocale="ZH-CN"
Update this entry to:
catalog productId="VS" productVersion="100" productLocale="EN-US"
a. Run powertool setup.
b. Revert the changes that you did in step (3) before launching Help viewer.
4.Install the Help Viewer Power Tool.
5.Go to your manifest folder under the help local store folder .
6.Open QueryManifest.*.xml file for edit
7.Update the branding package name to “dev10pt.mshc” - change:
1.This release is untested for non-RTM versions of Visual Studio 2010.
2.When browsing topics in content panel (in the browser), the URL in the address bar does not get updated.
3.When IE is not running with full trust privileges and viewing offline help, the Silverlight error message is incorrect.
Work-around: Update IE security settings to permit full trust privileges.
4.After the Help Viewer Power Tool is uninstalled, and customer browses to Help content, a 503 error message will appear.
Work-around: Close the Help Agent before uninstall process.
5.With the Help Viewer Power Tool installed, press F1 or view Help. If an F1 results in a 404, page will appear without the Index panel.
6.Offline help page does not display the TOC, Search nor Index for IE6.
Work-around: Upgrade to IE8.0
7.If the Help Agent is exited when setting "standaloneviewer=true" the Help Viewer Power Tool does communicate with the newly launched Help Agent instance.
Work-around: Close and re-launch Help content.
8.Self-branded content is not supported.
9.In the Chrome browser, the Back button is not enabled when you browse between contents from Index results.
10.Changes are not applied when running command “standaloneviewer=true” or “standaloneviewer=false” while Help Agent is running.
11.Setting “standaloneviewer=false” while the viewer is already running will result in .NET security exception.
12.In the search results panel, when using the keyboard down button to navigate the result set, and upon hitting a 404 page in local content, focus is moved to the search box in content panel - hence you cannot move down to the next topic in the results list using keyboard.
