[#WP8] Error installing Windows Phone #SDK


today I am dealing with an error which probes that even in a large and bureaucratic enterprise like Microsoft, move to fast makes you do some mistakes.

In my case I am trying to install Windows Phone 8 SDK and I meet the following error:

“A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file.”

WHAT ?!?!


After reading the installation log, I see that… the certificate with which the SDK is installed > is invalid!

To install this I’m using the original ISO file released almost a year ago (1.5 GB approx), kind of poorly packaged no?

Luckily for me, the solution is easy, download the SDK AGAIN from here and that’s it … unless you live in Mordor like me, and download 1.5Gb again is not an quick task.

By the way, nobody told you the fellow that temporary certificates… are, as temporary!
