WATK web download incompatible with latest WebPI (installer bug)

Question

I get the error "the web platform installer 4.0 is requried to be installed and version should be greater than 7.1.1586.1" when I run the WATK setup here:

http://www.microsoft.com/en-us/download/details.aspx?id=8396

This is a brand new machine running Windows 7 x32 bit, and I've reproduced this error on x64 and x32 alike.

This is a bug in WATK that makes it incompatible with the latest WebPI

Answer 1

Actually web platform installer is the tool that installs required software for all your web and azure developments. It pulls the components from MS and partners in a common UI. You can choose the components you want to install from the installer and it installs everything by downloading from sources.

Just install WPI 4.0. It helps you to install whatever you want.

Answer 2

Thanks, but let me clarify.

When I install the web download version of the Windows Azure Training Kit, it asks me to update a few components before I install the actual training kit.  One of the components to be installed as a prerequsite is Web PI. 

There is a version mismatch between the WATK and WebPI that prevents me from using the web download version of the WATK.

This is a problem that should be reported to Microsoft, so I'm attempting to do it here.

Hi Chris,

I couldn't reproduce your error in a clean machine. When I installed the Training Kit, it prompts me to download WebPI. I've downloaded it from the suggested link and re-launched the web installer without issues.

The message I got when I first launched it was:

"Oops.  The Web Platform Installer must be installed in order to use the Web Installer.   You can download the Web Platform Installer from http://go.microsoft.com/fwlink/?LinkID=254663.   Would you like to install it now?"

Your message was different:

"The web platform installer 4.0 is requried to be installed and version should be greater than 7.1.1586.1"

This error occurs when you already have an older version of WebPI (v3 or older) installed in your computer. If you already have uninstalled it, and you are still getting the same message, try removing the following key from the Windows Registry:

HKEY_CURRENT_USER\Software\Microsoft\WebPlatformInstaller

That should do the trick.
