Awesome content on Anatomy of an Enterprise Flex RIA

Folks,

I came across a superb 20 part series on developing an Enterprise level RIA using Flex, LCDS and EJB 3.0, written by Tony Hillerson and posted on InsideRIA. This series explains, in a good depth, about RIA trends, using Flex in conjunction with other tools, to develop a lightweight RIA environment. A must read for every budding RIA developer out there. Even an experience nerd will get quite useful content. Read it

Cheers!!!

Flash player installation woes in IE!!!

Hey Folks,

Ideally this is the first official post as it has come a long time after the first post. It took me as much as 6 months to get back 🙂 lame i know. Well, but things are settling down and I hope to be able to update this place more often now.

Now in this post, I am going to provide a simple solution for your flash player installation problems. Don’t expect it to be steps like first uninstall your current flash player, download new one, close browser windows etc… There are thousands of pages mentioning the same. However, I myself, with couple of my colleagues, were facing a weird problem. It was found that even after installing the player correctly, it would result in an error in Internet Explorer and it will never display the flash content in the browser, may what you do..

Upon digging, i found good piece of information (thanks to Adobe folks), which when implemented worked like a charm. To cut the story short, here are the steps:

First and the foremost, make sure your Internet Settings are set to allow the installation of ActiveX Controls. It is as simple as going to Internet Explorer > Tools > Internet Options > Security > Custom Level… and mark the ‘Download signed ActiveX controls’ and ‘Run ActiveX controls and Plug-ins’ options are set to Prompt and not to Disable. Don’t tell me you didn’t know it requires Administrative rights to perform this. Mostly after doing this too, it won’t work… If so, move ahead.

The main cause of the player not working / getting installed in IE is possibly due to a corrupt and damaged Windows system registry or incorrect permission settings in the registry. This prevents the Flash Player from being installed or registered properly.

Symptoms of a damaged registry or incorrect permissions may include:

  • Error during Flash Player installation:
    ‘Failed to install. For Troubleshooting please see: http://www.adobe.com/go/tn_19166’
  • Flash Player installer finishes with no error, but Flash content cannot be viewed in Internet Explorer.
  • Some sites tell you that you do not have the correct version of Flash Player, even though you just installed the latest version.
  • Some sites tell you to reinstall Flash Player, but after reinstalling the same message occurs.

Steps to resolve the issue (Administrative Privileges required):

  1. Download the SubInACL tool from the Microsoft Download Center.
  2. Install SubInACL.
  3. Download the reset_minimal.zip file.
  4. Extract the reset_minimal.cmd file to C:\Program Files\Windows Resource Kits\Tools\.
  5. *Important: Be sure that both the subinacl.exe and reset_minimal.cmd files are in the same location here: C:\Program Files\Windows Resource Kits\Tools\.
  6. Double-click reset_minimal.cmd.
  7. This will open a command window and execute the SubInACL tool.
  8. Do not use the machine while SubInACL is running.
  9. When it is finished you will see “Press any key to continue”.
  10. Install the Flash Player from www.adobe.com/go/getflashplayer.
  11. If the online installation fails, Download the executable version and run.

Once the above is performed, restart IE and to the best of my beliefs and wishes, it will load the Flash content correctly.

Windows Vista installation failure

On some Windows Vista systems Flash Player may be installed, but will not display Flash content. In some cases updating to the latest Flash Player using the included utility can correct the User Account Control settings that cause this problem.

To run the utility, find your installed Flash folder:

  • Right-click C:\Windows\System32\Macromed\Flash\FlashUtil9d.exe
    The letter changes with each Flash version, so may be “FlashUtilb.exe” or “FlashUtile.exe”
  • Select “Run as Administrator”
  • Follow the steps to complete the Flash Player installation
  • Restart your computer

Error while installing older version: The version of Adobe Flash Player ActiveX that you are trying to install is not the most current version

If you previously installed a later version of Flash Player for Internet Explorer, you may be prevented from installing an earlier version. For example, if you installed Flash Player 9,0,115,0, and attempted to install version 9,0,47,0 the installation would fail. In this case follow the instructions in “Safe versions security restrictions when installing Flash Player” (Adobe TechNote kb402435).

Hope it helps. Comments and any problems, if found, are welcome.
