As many of you already know, version 2 RTW of Web Platform Installer released in September. So what’s new in this version since RC that was released in March? First of all, Web PI now caches downloaded installers. Second of all, Web PI now supports 9 additional languages – German, French, Spanish, Russian, Italian, Japanese, Korean, Traditional and Simplified Chinese. This language support extends to both displaying Web PI UI in the language of the current OS locale and installing a product (if available) in the language specified by the user. Finally, the last biggest feature of RTW is extensibility.
All the new features are surfaced through the Options dialog, which is also new in RTW. Here is a list of new features surfaced through the dialog:
- Additional scenarios
- Installer caching
Some of these features are rather too big to include them in one article and are described separately through the links provided in each title. Thus, this article will cover only the remaining features surfaced through the Options dialog
- Installer caching, and
- Resetting the options
In previous versions of Web PI, if installation fails for some reason and the user has to start installation again, Web PI would have to download the selected product again in order to start installation. This version of Web PI caches downloaded products in case it would want them again. Thus, every time you install something it gets cached under
%LocalAppData%\Microsoft\Web Platform Installer\installers
If installation fails, you can always run the cached installer that is likely to have a UI that might surface the errors better. Also, if you want to install the same set of products on a different machine, you can just copy the installer cache folder to that machine to the same location and Web PI will pick it up. No worries if an installer gets updated for a product, since Web PI will compare the time stamps and download the newer file when you request to install the product again. The size of the cache is always shown in the dialog. If it gets too big or you don’t find it useful anymore (everything installs fine), you can clear the cache by clicking on “Delete installer cache folder” hyperlink.
Resetting the options
From the command line you can launch Web PI with a /reset switch that will restore your options to the default state:
"%ProgramFiles%\Microsoft\Web Platform Installer\WebPlatformInstaller.exe" /reset
