Windows 10: program will not open- change file type associated with a file extension

I went to control panel, file, and when I click on "change the file type associated with a file extension" the window opens with the blue screen and the file icon in the center but never actually opens up at all.

:)

 

Can a file extension(.flv) be added to Default Program Associations.

Hi Fred,



Thank you for posting your query on Microsoft Community.



I understand that you are facing issues associating a particular file extension with a program on Windows 10. I apologize for the inconvenience caused to you.

To assist you better, please provide the information:

When you say that "Default Program Associations", are you referring to the list of default applications in default programs settings?



I want you to be informed that all the file extensions is listed in the default program settings which is displayed under
Associate a file type or protocol with a program.



In default program list, all the programs or application will be listed. Then we can select each program as default program for opening a particular file.

I suggest you to refer to the below steps to make default program for a particular file extension.

1. Type "Control Panel" without the quotes in search box and click on it.

2. Click on Programs.

3. Then click on Default Programs and click on Choose Default for this Programs.

4. Select .flv file from the list.

Also you can try other steps to associate the a particular extenstion with the program.

1. Type "Control Panel" without the quotes in search box and click on it.

2. Click on Programs.

3. Then click on Associate a file type or protocol with a program
and search for .flv extension from the list.

4. Click on .flv and then click on Change Program.

File type associations not launching the program in the list


This problem has just started on several machines since 8/20/2016. On Windows 10 Pro computers, the program associated with a file type extension will not launch correctly anymore even though the correct program is listed as associated with that file type.

I have seen two versions of this issue. On one machine, double clicking on a file in Windows Explorer with a .xls extension would open Excel but the worksheet would be blank. If you open Excel first and then load the file from within Excel, it opens fine.

On another computer, double clicking on a file with an assigned file extension results in nothing happening.

I have been able to solve this problem by going to the "Control Panel" --> "Default Programs" --> "Associate a file type or protocol with a program" selecting the file extension I need to work, click "Change Program..." and select the same program that was already listed as the "Current Default".

Obviously, the program listed as the current default is no longer associated with the extension in the registry.

The next time I see this behavior, I will check the registry entries before I apply my "fix".

I just wanted to know if others are seeing this issue and what is causing it.

2) Next Open Control Panel (icons view), click/tap on the default programs icon.

3) Click/tap on the Associate a file type or protocol with a program

4) Either double click/tap on the file extension or protocol, or click/tap on the file extension or protocol and click/tap on the
Change Program button of the one you want to change the "current default' program association of.

5) If the program you want to associate is not listed, then click/tap on the
More Options link if available.

6) Click/tap on a listed program that you want to associate.

7) If you associated a program, then you will see this below as "Set Associations" updates and reloads.

8) Once it is done go back to the file which you have created and delete the file.
