Ever since I got a new Acer laptop, an Aspire, two years ago with Windows 7 Home Premium, and I transferred my old files to it, I’ve been unable to open certain files that I receive in email: JPG, PNG, or PowerPoint presentations. I get this message that basically says, “The file .jpg could not be opened because the associated helper application does not exist. Change the association in your Preferences.” Can you explain what this means and how to correct the problem? I work around it by saving the photo, going to the folder I saved it in, and then opening it the way that I would any file or photo.
It’s odd that you can view the files after saving them. That implies that you have the program that you need to view pictures.
Unfortunately, you didn’t mention the email program that you’re using. That plays a key role in this problem. Let’s talk about what’s going on here.
How can I create an association in Folder Options? I get this error message when attempting to open picture attachments on Outlook Express: “This file does not have a program associated with it for performing this action. Create an association in the Folder Options control panel.”
A file can contain anything. Under Windows (and under MS-DOS before it), the convention was established that the characters following the last period in a file name, called the file “extension”, tells you what kind of data that file contains. “.EXE”, for example, is an EXEcutable program. “.JPG” is a jpeg compressed image file, “.TXT” is a plain text file, and so on.
In addition to knowing what type of data a file contains, Windows also needs to know what program should be used to access that file.
If that information is missing, then “This file does not have a program associated with it…” is one of the possible error messages.
