Error 104 The certificate specified has expired. For more information about renewing certificates, see http://go.microsoft.com/fwlink/?LinkID=241478.
It turns out that this is an issue with the underlying Cordova support for Windows 8, which contains a recently expired certificate - as explained here. The certifcate expired on 11/11/2014.
UPDATE 1/18/2015: It appears the issue appeared again with another expired certificate. Please see this post for details on how to correct the issue for a single project (option 1) and for all projects (option 2)
The VS Tools for Apache Cordova (CTP3) picks up this certificate file on build from a subfolder in the \Users\ directory, and this is what fixed the issue for me...
- For CTP3, go to the following directory:
c:\users\{yourUsername}\.cordova\lib\npm_cache\cordova-windows\3.6.4\package\template\CordovaApp_TemporaryKey.pfx - Using Visual Studio, create a new Windows Store "Universal App" - this will provide you with an unexpired key file, which will be located in the \BlankShared.Windows subfolder of the project.
Make a copy of this file:
BlankSharedAppX_TemporaryKey.pfx
... and rename it to
CordovaApp_TemporaryKey.pfx - Backup the following PFX file (just in case) and then copy over the newly created PFX file in its place -
c:\users\{yourUsername}\.cordova\lib\npm_cache\cordova-windows\3.6.4\package\template\CordovaApp_TemporaryKey.pfx - Back in VS, do a build / Clean and then a Rebuild.
Anyway, that worked for me. Good luck!
