iOS application installation fails

[premun]

I tried with an app bundled by XHarness as well with Egor's.

I get an error from mlaunch:

• mlaunch didn't change
• test app didn't change
• iOS version didn't change
• only XHarness changed, but not sure when this started..

Trying to find when it started

I have tested with the latests preview version, the app installs and launch perfectly. There are two possible issues for this:

1. The application has a funny name (_ in it)
2. The certificates you are suing DO NOT match the bundle id (this is the most probably case).
3. Some crazy cert issues.

I would try to run the app with vsmac of xcode to see if the same happens.

I guess the issue was that folder name was different than app name
