I checked the subErrorID, which reports 16827, " The version contained in the update file does not match the version from the update descriptor."
I assume "update file" here is the update.xml file I placed on my server (in the same directory as the Air application file). I assume the "update description" mentioned is the Flash Builder auto-generated Air Application Descriptor file (with name myappname-app.xml placed in the bin-debug directory). The producer I use is, first I clean the project, then I edit the version number in the application descriptor file, then I export the project, and move it's .air file along with update.xml to my server. In both places I have: < versionNumber > 12 </ versionNumber > I can verify update.xml on the server by visiting it in a browser. Now I'm wondering if this versionNumber should be located somewhere else? Is update.xml supposed to be included in the project directory somewhere? Currently I've just been creating it outside Flash Builder, then moving it along with the final .air file to my website for download. Any idea what else I can check? ----- Original Message ----- From: "Felipe R.
