Install 2.0.333.1 fails due to signature verification

Jul 20, 2012 at 3:44 AM

I've downloaded and trying to install the latest version (2.0.333.1 16-July) but I'm getting an error:

This Product did not install successfully: Download file failed signature verification and may have been tampered with.

when I look at the install log, it looks to be referencing the wrong version

Thanks for trying our solution.

We did test on a clean machine and can't reproduce this issue :(
Did you try the previous version (#2.0.2267.1) ? Web Platform Installer, may have some cache and keep the previous version. Could you clear the cache of Web Platform Installer and the cache of Internet Explorer and try again ?

To clear the Web Platform Installer cache, run it and in the options dialog, you can clear the cache :
