AIR auto-updater -- include markup?

I have had my AIR application able to auto-update for some time. But I'm wondering if you can somehow include HTML in the description you see of the auto-updater. Here is my update.xml file on the server:
<?xml version="1.0" encoding="utf-8"?>
<update xmlns="http://ns.adobe.com/air/framework/update/description/1.0">
<version>1.0.0</version>
<url>url-to-air-installation-file</url>
<description><![CDATA[Text of new things in this version.... ]]></description></update>
I've tried to remove the <![CDATA[ and use HTML inside the <description> block, but it doesn't work. Am I missing something? Is this even possible??
Thanks,
Ian

if u are using code to display veesion number make sure it should look like:

Air Auto Update Error -- Flash Builder Burrito.

This is my first attempt at this, so I may be missing something simple.
I'm not having any luck getting an Air app to automatically update.
If I manually go to http://localhost/air1/air1.air and redownload the file I will get a popup that asks if I want to update the app, but when I say ok I get this error.
"There was an error checking for updates. Error# 16816"
I haven't found a reason yet,
Any ideas?

AIR Auto update error

Hello all,
I am trying to build an autoupdate app in AIR using FB4. I use the code :

        import air.update.ApplicationUpdaterUI;

AIR auto update error, and question about POST parameters

Hello,
I'm getting a Download Failed error in the AIR autoupdating process;
There was an error downloading the update. Error# 16822
I recall this working once, the very first time that I tried it.
My app.xml file contains this line:
    <version>12</version>
and my update.xml file contains:
<update xmlns="http://ns.adobe.com/air/framework/update/description/1.0">
<version>12</version>
<url>http:/players.biemedia.com/ooyala/Composer/Composer.air</url>
<description>12 - Bug fixes and prepopulating defaults for player creation screen</description>
</update>
Pasting the URL into a browser works.
However, this stuffresides on cloudfront. in the past i have noticed that if something tries to send post parameters along with the request, cloudfront will deny the request. Is it possible that the AIR app is sending POST parameters when hitting the download URL, and could this behavior be new in the last 6 months or so?
Any other ideas?
Thanks,
Gerry

Windows XP Permissions vs AIR Auto Update

Hello All,
I've just started getting into AIR, and I've run into an
issue. I'm planning an app that would be distributed to Windows XP
users with limited accounts. The issue I'm currently trying to
tackle is how to get the application to auto update when a user
opens it from a limited account. Currently it gives me the error:
"An error occurred while updating the application. Try updating it
again. If the problem persists, contact the application author.
Error# 0".
Since I'm a Mac guy, I don't know too much about permissions
and account settings in XP. Is there a way to simply give the
application the necessary permissions without having the user have
to login every time like the "Run with different credentials"
option.

No, there's no way around this. Prevent applications from
updating themselves is part of what limited accounts are supposed
to do.
You might try finding out how software is normally updated
for these machines. That's probably the path you want to take for
this application, too.

Why doesn't AIR auto-update

How to setup air help auto-update

RH8 HTML.
Im fiddling around with the AIR Help file and trying to get the auto update working.
So far I have the comments syncing perfectly across users with a shared folder on our network.
I'm now publishing the air file to a shared folder again where everyone can get the file and where the update.xml file is sitting.
so I have this looking structure.
\\networkdrive\Adobe_AIR\Generic_AIR\AdobeAIRApplication\Help File.air
\\networkdrive\Adobe_AIR\Generic_AIR\AdobeAIRApplication\Help_Update.xml
I set everything in RH Air output to publish to these folders, and I can see the newest files each time I do, I change the version numbers from 1.28 to 1.29, and this is reflected in the update.xml file where the version number has changed.
but when I go into the actual instaleld 1.28 version and use the Check Now feature to look for the latest 1.29 which has over written the 1.28 files in the shared folder, it finds nothing.
I cant find any way to manually point to where the update should be found.....do the update files have to sit in the same install directory or something? How does this work....aarrrgghhh
Is there another things I'm not doing?
Thanks.

Hi Nick
Good to hear that you are looking into AIR and Comment syncing is working fine.
Regarding the AIR auto update feature, you need to do the following
While generating the AIR file, you need to specify the update XML file location in AIR Help SSL generation option shown in the image below.
Now install this AIR file, and update the update.xml file and new version of AIR file, and it should work fine.
So the point is the installed air file need to know where to look for the update.xml file, it can be shared folder or a website.
Hope this will help you.

Authenticating AIR application auto-update

Hi, I'm building documentation for my desktop-product with RH8 and AIR SSL auto-update functionality. It looks like I need to expose any revision of my documentation on Internet for the auto-update. My company does not want to expose it freely since it is intellecual property. Is there a way to protect the revision with some authentication that would work with the AIR auto-update mechanism? Thanks in advance.
--dh

Same situation like ours! :-)
If your documentation on the internet is accessed using "https", then that's the link that will be used for auto-updating and thus an authentication box will be displayed anytime a request for an update is made.
Good luck.

Best practice for auto update flex web applications

Hi all
is there a best practice for auto update flex web applications, much in the same way AIR applications have an auto update mechanism?
can you please point me to the right direction?
cheers
Yariv

Hey drkstr
I'm talking about a more complex mechanism that can handle updates to modules being loaded into the application ect...
I can always query the server for the verion and prevent loading from cach when a module needs to be updated
but I was hoping for something easy like the AIR auto update feature

How to use auto update in android ?

hi,
i want to use adobe air auto update in android devices.. what can i do ?

Did you install the maintenance service properly in download and install updates in the background?
*Tools > Options > Advanced > Update: "Use a background service to install updates"
*https://support.mozilla.org/kb/what-mozilla-maintenance-service
If updating Firefox isn't working properly then this could be that the maintenance service isn't installed and enabled properly or not allowed in security software.
The maintenance service can be uninstalled separately, it shows up as a new item under add/remove programs.
You can try to uninstall and reinstall the maintenance service as a user by running the installer file in the Firefox program folder.

Adobe Air runtime auto-update

Adobe Air runtime auto-updates itself without any notification or request on my Mac OSX 10.6.7 machine. I do not like this behavior. Is there any way to change it?

Please see our Disable automatic updates of the runtime document. However, please be aware that our updates include both new functionality and bug and security fixes. I'd definitely recommend keeping an eye out for future releases and manually installing if you disable the updates.
Thanks,

Why don't you post some of the relevant lines for your application?
Makes hard to guess what the issue is otherwise.
The first line of your matching app file (<appname>-app.mxml) must have the same matching air sdk version as in...
<application xmlns="http://ns.adobe.com/air/application/2.6">
The version number if that same file must match the versionNumber in your update file, as in
<versionNumber>0.0.4</versionNumber>
Compile it and distribute it to the url specified in your update xml file
http://www.abc.com/updates/RixossIBoard_v004.air.zip
Manually check your app:/update_config.xml - make sure it is what you think it is

Flash Builder 4.5.1 - Air ApplicationUpdaterUI Auto Update Fails

I just reinstalled my FlashBuilder 4.5.1 and built a new HelloWorld App
in order to test the SDK 2.6 with the Air ApplicationUpdaterUI.
I get no errors but it won't update using the 2.6 namespace in both the -app.mxml and update.xml on server.
A trace in the StatusUpdateEvent never shows up in debug mode.
The only window that pops up is the one asking to Check for Update?

Bolded appl descriptor versions
Message was edited by: DonMitchinson

Status Update - don't know if this is a bug, design flaw, install problem or my misunderstanding.
I got it to work by first changing my Flex library to 4.5.0 - still didn't work with current
app and update mxml files using "2.6" for their namespace versions. But I did at least
get the popup error number 16815 - indicating an error in the update version namespace.
By leaving my application namespace version at "2.6" and changing the update version to "2.5" ... bingo!
I got my new update installed autiomatically.
Is this how it's supposed to work - or are my runtimes mixed up?
Will this work the same using the Flex 4.5.1 SDK? I'll find out shortly
Hope this helps others.

Hi Jayagopal,
The error you are getting might be from the fact that you are using an invalid namespace within your update.xml. Can you make sure that the specified namespace from the update.xml is the same with the following one xmlns="http://ns.adobe.com/air/framework/update/description/1.0" and then then try to reproduce this issue?
Here is the update.xml which i've used when trying to reproduce your issue:
<?xml version="1.0" encoding="utf-8"?>
<update xmlns="http://ns.adobe.com/air/framework/update/description/1.0">
<version>v1.1</version>
<url>http://localhost/AutoUpdate1/update.air</url>
<description><![CDATA[
Version 1.1. This new version includes:
    * Feature 1
    * Feature 2
    * Feature 3
]]></description>
</update>
If you can still reproduce this issue can you also attach your update.xml or host your air app and update.xml on an external server from where I could access them?
Hope this helps you,

Use the system lang of AIR applications auto update.

Hello,
I recently used the auto update framework for my AIR application, this works fine but i have a small problem.
I made some reasearches and i found AIR uses the system lang by default. When i install my package for the first time, the lang is my sytem lang but when i find a new update after running auto update of my app, the AIR updater window doesn't use my sytem lang, which is french, but uses english lang. I'd like to put this window in french.
Thanks.

Try loading and using the add-on from this link: https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/
Many add-ons do in fact work if you force them to run. The procedure to roll-back is given in this article: [[installing previous versions of firefox]]
Unfortunately the official Firefox policy is that you downgrade to 3.6 which is supported for a while longer, and not the now unsupported Firefox 4. If after installing and running the ''add-on compatibility reporter'' you still have problems there are ways around the official policy.
I think it is absurd that Firefox 4 may be used by tens of millions of users one day and a few days later those that upgrade to Firefox 5 should be not only told not to use a now unsupported browser, if they need to revert due to problems, but are actually obstructed in attempts to do so.
