I\'m almost dead now. I\'ve been trying for about 2-3 weeks to fix that problem, but still no result. Hope anyone is able to help me:
I\'m writing iOS Apps with Tita
I had the same “Unable to download application. 'Appname' could not be installed at this time” message, and spent several weeks checking and renewing the certificates, rebuilding, re-doing the OTA distribution, etcetera. It turned out that I simply hadn't added the .mobileprovision files to the project. Just in case this helps anyone…
