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!

Thank you.

    Hello Rdforbe,

    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.

    To find out if your computer is running 32-bit Windows or 64-bit, follow these steps:
    System opened by clicking on the button start , by clicking on the Control Panel, click System.
    Under system, you can view the system type. This will describe if you have 32-bit or 64-bit.

    You can also try compatibility mode.

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

    Use the following steps:

    (1) right click on the program

    2) click Properties

    3) click on the Compatibility tab

    (4) select run this program in compatibility mode and select Windows Vista or other operating system, the program has been run successfully.

    Given that the game is compatible with Windows 7, I suspect that the conflict can be 32-bit or 64-bit architecture.
    The link below shows the compatibility of this game with Windows 7.
     
     
    Method 1.
    We must ensure that the edition of the game must correspond with the operating system.
    If you use 64-bit in this game, you need the 64-bit Windows to install it.
    Method 2.
    If the above information matching I you recommend to start the computer in clean condition and then try to install the game.

  • is not compatible with the version of windows you are using, with X 86 or X 64

    My son downloaded something and now I can't use anything on my computer, I get "not compatible with the version of windows that you are using, with the X 86 or X 64... I uninstalled it but it will not go away, I tried to do a system restore, but I get the same error... ideas?

    What antivirus you typed the problem started?

    It seems fishy to me, it could be a virus that has been downloaded at a given time, perhaps even until this program was installed. I would try an online virus scanner.

    And: http://quickscan.bitdefender.com/en/ (from what I hear, it removes something fishy, so be careful!)
    It should work with IE (Internet Explorer).
    Curiously, the ones I tried before I could not find, so I did a quick search and these look good.
    I forgot to ask sooner, but you can open command prompt (start > Accessories > try click right-click on command prompt, and then run as administrator)?

    Windows 7 will not be included within the compatibility list, because you are already using Windows 7. Your only option is to contact the Publisher of software (the company that built the program) and get a version that works with your computer type (64 bit or 32 bit, whichever one you have).

  • Is my MacBook Pro 15 "end 2013 compatible with Thunderbolt 3 devices (if you are using an adapter)

    I have a MacBook Pro 15 "end of 2013, 16 GB, 1 TB SSD, 2.3 GHz i7 running OS X 10.11.4." My SSD is maxed out so I plan to buy a box 2 Berry drive Thunderbolt and secure it with a 1 TB SSD.

    I know Thunderbolt enclosure 2 still available, but lightning 3 cases are starting to hit the market. I wonder if a Thunderbolt 3 box will be compatible. Because I'll probably replace it the MacBook Pro 12-18 months and I assume - rightly or wrongly - that Apple will adopt 3 bolt of lightning on the MacBook Pro, Mac Pro and iMac during this period, I would prefer Thunderbolt 3 for scalability.

    I am aware that the cables are physically different, and 3 bolt of Lightning has adopted the USB - C standard. My question is: if I buy the cable or a suitable adapter, I'll be able to use a box Thunderbolt 3? (I know there will be no performance difference; however, it is scalability).

    Thunderbolt 3 is backward compatible with earlier versions of Thunderbolt.
