Hello,
I'm also running into the same issue. Looking at this thread, I went to check on my development machine license and it seems that it has expired (the licensing page on my Esri Developer account says it expired on April 8, 2014, but I was able to run a Qt program using the ArcGIS Qt SDK on the 10th), but when I try to renew the license via the Software Authorization Wizard 10.2, it results in
"7174:Only deployed entitlement line item can be fulfilled."
And the authorization fails. Any suggestions on how to renew the license?
