Microsoft Help Viewer 2.0

What is Microsoft Help Viewer?

Microsoft Help Viewer is the offline help system (local help) developed by Microsoft that ships with Visual Studio. The user experience for Microsoft Help Viewer 1.x is that topics can be viewed in any installed web browser – a separate application, such as the Microsoft Document Explorer included with Microsoft Help 2, is not necessary. The browser-based model is meant to provide a more lightweight navigation, downloading, and reading experience than earlier help-viewer models.


The most used version is 2.0.50727, with over 98% of all installations currently using this version. Upon installation, it defines an auto-start registry entry which allows the program run on each boot for the user which installed it. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The main program executable is HlpViewer.exe. The software installer includes 6 files and is usually about 11.18 MB (11,721,360 bytes).
