Can't deploy to device

[skumancer]

So, I have had a problem deploying an executable to all of my devices since the first UDK version I've used (December 2011).

I use this same set of Provisioning Profile and Certificates to deploy applications from XCode without any problems, so I don't understand what's wrong.

Here is the output of the frontend:

Saving IPA ...
 ... Writing updated Info.plist
Opening source executable...
... Initial signature step
IPP ERROR: Application exception: System.Security.Cryptography.CryptographicException: Keyset does not exist

Any help would be greatly appreciated. I have already tried regenerating new versions of both certificates and Provisioning Profile, re-installing UDK (I'm on March 2012).

My answer was to create a new certificate with the Signing Request (csr) generated by IPhonePackager utility, and my old keys.

This worked and now I can deploy to my devices.

My solution to this also involved resigning a certificate, but I just went to the iOS Dev portal. I also had to export a set of keys from my Keychain assistant in OSX. Be very careful to do it from the certificates page.

After this, I thought I was done, which led me to your post. I also had to go to the iPhonePackager utility and bring in my encrypted key created in OSX. Crazy, since it would work from Frontend, but I'm not complaining.
