Hi VikkHckrz,

1. you remember to make changes to the computer recently?

Method 1:

You can consult the following KB article and run the fix it tool available and check if you can assign file association.

When you run an .exe on a Windows Vista-based or Windows 7 computer file, the file may start another program

http://support.Microsoft.com/kb/950505

Also check out the link:

http://Windows.Microsoft.com/en-us/Windows7/change-which-programs-Windows-uses-by-default

After running the fixit so check the option is grayed out or not.

Method 2:

If you're still having problems, then you can try to change the settings in the registry only if it is present on your computer and check if it helps.

a. Click Start, type regedit in the search box and press ENTER.

b. navigate to the

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer

(c) in the right side of the screen, double click on "NoFileAssociate".

d. change the value of "NoFileAssociate" from 1 to 0.

e. exit the registry editor and restart the computer and check.

Important: The above mentioned steps show you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs.

For more information about how to back up and restore the registry, follow the steps from the link below:

    You can do this via a registry change, but it is more appropriate for a typical user to simply use the system restore:

    Ever wished that you can go back in time following a bad fall? With Windows, you can.

    Installation sometimes a driver or a program can make Windows run slowly or erratically. System Restore can return programs and system files from your PC to a time where everything worked, potentially prevent hours of troubleshooting of headaches. This will not affect your documents, images or other data.

    In Windows 7, you can create system restore points more and see exactly what files will be deleted or added when your PC is restored. For more information, see create a restore point.

    For more protection, use the restore system backup and restore, which is designed to help save email, photos, documents and other personal files.

    To use the system restore

    Before you start the system restore, save open files and close all programs. System Restore will restart your PC.

    1. Open system restore by clicking the start . In the search box, type restore the system and then, in the list of results, click on system restore.  If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
    2. Follow the steps in the wizard to select a restore point and restore your computer.

    Hello

    I would like to know the operating system you work with.

    Method 1) when you run an .exe on a Windows XP, Windows Vista or Windows 7 computer file, the file can start another program

    http://support.Microsoft.com/kb/950505

    Method 2) in case if it does not help, you must change the associated file. To change the file association for a specific file, you must first display the properties of the file.

    1. You can view the properties of a file by selecting the file and choosing 'Properties' in the file menu. Or you can simply right-click on the file and select "Properties" from the context menu that appears.
    1. To change this file association, click the button change.
    1. You are given a list of recommended programs to open the file, as well as several other programs on your computer. The recommended programs are programs that Windows knows is going to be able to open the current file type. For this reason, choose a program from the list of recommended programs is a good idea. You can choose a program from the list of other programs, but the file cannot open.
    1. You can change this program opens all documents of a certain type of file, and then click the checkbox "Always use the selected program to open this type of file."
    1. Click OK

  • Restoration of openers program: how to restore the original program of opening such as internet explore and itunes instead of notepad ++

    on my computer, I have somehow changed the settings for applications on windows 7 open with notepad ++ how to restore the original program of opening such as internet explore and itunes instead of notepad ++

    I've seen this happen when opening a program via a shortcut (for example. LNK file), you are asked what type of program to open it with. After selection of Notepad ++ (or another program) via the Select a program from a list of installed programsand checking the always use the selected program to open this type of file, document or program referenced by the shortcut of origin opens in Notepad ++ as it should.

    The problem is that now all shortcuts (for example. LNK files) on the desktop or in the browser will want to open Notepad ++ and use the icon of Notepad ++ to display the shortcut no matter what shortcut was originally intentioned to open. This is known as a file association and the default icon.

    The good news is that a small free utility was written to cancel the. LNK file association was created. There is also a registry hack to achieve, but I recommend the utility unASSOC for its ease of use.

    A utility to Unassociate Types of files in Windows 7 and Vista

    Just download and then use the utility to unassociate the. LNK files. Manual is available on the web page above (the same place to get the utility). Quite simply, you run the program and wait for the list of the types of files to complete. Select. LNK in the list and then click delete the file type.
