Adobe Flex Air error #16824

Tried out the ApplicationUpdaterUI and received error 16824 when my application tried to do the update.

Found out that the solution was to have the exact same string in your tag in the “appName-app.xml” file and in the “appNameUpdate.xml” file on the web server.

The error code might handle other issues but this solved it for me.

    Talking about the version tag in “appName-app.xml” in the Flex project and the same tag in the XML file you put on the web server.

    Lol. Maverick wondered what tag you talk about. You talk twice about a tag, but you never mention which one you mean.

    I guess fdqps means the version tag.

    so you mean:

    v1 changed to appName?

    and the application-app.xml:
    v1 changed to

    i’m confused… i’m having this issue too, but i use the version tag to see what version i need to upgrade to…

    Thanks for your comment, I think. Could you translate it to english?
