Application using Java SDK 5.0 compatible with the lower SDK version?

Hello

I wanted to know if I'm developing an application using the Blackberry Java SDK 5.0, it would work on slot version 4.3 or 4.2.1? If the current application has features not available on the previous version of course.

I mean, if I develop an application of basic as a HelloWorld with SDK 5.0, this app works on a phone with SDK 4.2.1?

Thank you

Damien.

The only time where I tried it, I received an error of compatilbility so I would say not in my experience.

My suggestion is to build with backward compatibility in mind and remember that what you build for 4.2 will work in 5.0 and so on.

    Hello

    Do a clean install of XP with the XP disk provided by Dell, if you.

    http://pcsupport.about.com/od/OperatingSystems/SS/instxpclean1.htm

    If you do not have your XP disk, you can contact Dell and ask them to send you a XP disc.

    They should do this for a small fee.

    You need to change the Boot order to make the DVD/CD drive 1st in the order of startup and startup disk:

  • folder "is not compatible" with the photoshop cs6 version, but was created in the cs6 version!

    3 Photoshop PSD I created last week. Recorded 3 PSD in the same location on my computer and created in the same version. Today, I'm going to open all 3 and all but 1 opens. The 3rd file says "cannot complete request because the file is not compatible with this version of photoshop". I don't have a newer version, or I changed nothing. Anyone know how I can fix this problem?

    I was able to contact a technical support person and they tried to open the file in the newer version, however, they also said that the file is corrupted. Fortunately I sent me an e-mail that day from the PSD. I had to download from my e-mail address and opened it right. Not to self: save files in multiple locations, and sending the e-mail to yourself has been a lifesaver!

  • Win2K8 - this processor is not compatible with the 64-bit mode

    This is my first shot to create a virtual machine VMware

    We just got a new server in a data center

    Its windows 2008 Server. (the 64-bit version)

    My plan is to run a Server 2008 ontop of a host of Server 2008 virtual machine

    First I used a converter for P2V - this bit has been successful, so basically I took a picture of the host and converted to a Virtual Machine.

    I put the image to use 1 core of the dual core CPU and the memory (4gig) half and half of disk space on drive D (50 GB)

    Then I installed virtual server 2, and any

    Then I installed the thing that makes you see the window in Internet Explorer (some may be active x thing?)

    In any case, at the time of starting the server VM, I get the message:

    Windows could not start. A recent hardware or software change might be the cause. to solve the problem:

    I'm a little confused on this, the server is located in a datacenter somewhere and I don't think that the CD option is viable, because they will probably be responsible for a lot of things to do

    Any ideas what I should try?

    the cpu is 64-bit but because I split at the image, I'm not sure if that is break things

    Any advice appreciated

    Thank you

    You can run virtual servers, they simply can be 64-bit because your processor doesn't support VT

  • Firefox wants to update (again!) now at version 6. How will I know that my extensions are compatible with the new version?

    I checked with the developer of the extension sites, but they do not yet report if the extension has been tested with Firefox 6.0. 3.6-4.0 switch left me with a gap in functionality of my extensions, although the switch of 4.0 to 5.0 went smoothly. I remember that the installer for 4.0 tested my extensions for compatibility before asking me to confirm if I wanted to install. 6.0, however, says he is already downloaded and just waiting for me to restart Firefox. Mozilla seems to be getting less polite and more aggressive on updates.

    When Firefox starts to install the updated version, it shows you the Add-ons that won't be Compatible with the new Firefox version that is being installed. You can cancel the Installation at this stage.

    I'm not sure about this, but you can also use - Add-on Compatibility Reporter 0.8.7

    Check and tell if its working.

  • Firefox worked, today has not started with the error the version of this file is not compatible with the version of windows you are using.

    Computer is Windows 7 Ultimate 64 bit. Firefox has work fine for over a year on this computer. Nothing has been changed or updated updated except Windows update indicates that it installed updates on August 19. I had computer week before because only out of town, back entrance and began August 18, but Firefox has worked that day. Does not use FF again until today. Today August 22, firefox does not start, shortcut icon changed program not there. Exe in the folder when you click Poster error message says the version of this file is not compatible with the version of Windows, I am running. Exe of Firefox shows created on 20 August. I suspect the update, Windows or FF but lean towards windows, which was spent, who broke things. I noticed that IE 10 updates, updates of .NET framework and the malicious software removal tool have been installed. I tried to restart the computer, has not set. Tried to run as administrator, did not work. I don't want to uninstall FF, at least have to because of all the things I have here, bookmarks, last past passwords, etc..

    Hello

    Some Firefox problems can be solved by performing a clean reinstall. This means that you remove Firefox program files (not the profile folder, where the bookmarks are stored) and then reinstall Firefox. Please follow these steps:

    Note: You can print these steps or consult them in another browser.

    1. Download the latest version of Firefox from http://www.mozilla.org office and save the installer to your computer.
    2. Once the download is complete, close all Firefox Windows (click on quit in the file menu or Firefox).
    3. Remove the Firefox installation folder, which is located in one of these locations, by default:
      • Windows:

        • C:\Program Files\Mozilla Firefox
        • C:\Program Files (x 86) \Mozilla Firefox
      • Mac: Delete Firefox in the Applications folder.
      • Linux: If you have installed Firefox with the distribution-based package manager, you must use the same way to uninstall: see Install Firefox on Linux. If you have downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
    4. Now, go ahead and reinstall Firefox:
      1. Double-click on the downloaded Setup file and go through the steps in the installation wizard.
      2. Once the wizard is completed, click to open Firefox directly after clicking the Finish button.

    Please report back to see if this helped you!

    I get this message when you try to run an old MS-DOS - based program in Win-7 Ultimate 64-bit.

    "The version of this file is not compatible with the version of Windows you are using. Check your computer system information to see whether you need a x 86 (32 bit) or x 64 (64-bit) version of the program and then contact the software publisher. »

    I understand that I am under a 64 bit OS, but is it possible to get this program to run? I was wondering if anyone has tips :)

    Hi Bcopeland,

    Thanks for posting your question in the Microsoft Community.

    Based on the information, you are trying to install and use an old ms - dos program based in Windows-7 Ultimate 64-bit.

    The problem is a software that was created for Windows 95, 98, and Windows XP has no way to work correctly with an operating system that didn't even exist when the software was written. However, the error message you get normally means that you have a 32-bit software that you are trying to install on a 64-bit system.

    You can check the compatibility of the program with Windows 7, in the Compatibility Center.

    Compatibility Center

    If the program is not compatible, then you try to install and run the program in compatibility mode.

    a. click right on the program.

    b. click Properties.

    c. click on the tab compatibility.

    d. Select run this program in compatibility mode and select Windows Vista or whatever to use the system, the program was executed successfully.

    Here is an article that gives you more information on this:

    Make older programs in this version of Windows

    If the problem persists, you can get in touch with the software vendor to see for the latest version of the program to use the same system of 64-bit Windows 7.

    Hope the helps of information.

    If you need assistance in the future to resolve any issues related to Windows, post your query and we will be happy to help you.
