"Unable to Download Application" (Solution: Expired or incorrect provisionings)

When I click the link from the build mail I get this message during install.
Had this problem a lot yesterday, then it suddenly worked, but now it's back again.
What's the problem?

You only need to install stencyl once and then do any subsequent update (like 2.2). Has that been successful for you?

Yeah, that's no problem (got the nightly build from yesterday). It's the iOS application from the mail that won't install. It goes to ~70 percent.
No problem installing regular apps.

i have this problem too... any solutions?

//EDIT:  stencyl version 2.1 works good. You should fix it in 2.2. Thanks

same here....any solution?

Someone pointed this topic out to me. I'm answering it for the sake of anybody who searches, hits this topic and hasn't seen a solution.

The error is misleading and has *nothing* to do with downloading or the file being incomplete. It is not a bug in Stencyl.

It's a common error indicating that the provisioning profile, installed to the device or embedded in the app is incorrect/incompatible/expired. It's a shame that the iOS error message doesn't present this better.

Common causes
- The device you are installing on isn't included in the profile.
- The profile has expired.
- The profile was revoked.
- You embedded the app store profile, versus the ad hoc profile.
- The app you are building isn't part of the profile.
