Webmatrix Gallery Error

I've started several Orchard sites from Webmatrix Web Gallery, but then suddenly it stopped working.  I can't use that capability to make any further sites (and yes, this is all on the same computer, on the same network).  After I accept the EULA, I'm told:

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

I've searched for this problem, and found that many other people have had it (with Wordpress and other items).  The solution I've seen posted elsewhere is to open web platfrom installer, select 'options', and clear the download cache.  I did that step, and then restarted webmatrix - but it did not solve the problem.

The installer log given by webmatrix is this:

Clear your IE cache.

That worked!
