Not surprising since that is usually an export file that then needs to be imported to something like Excel.

What program is this exported from?

I think the problem is that the file type .csv is associated with an invalid program. When you try to open the csv file, Windows tries to start the associated program, and because that is not a valid program, that's why you get that message.

Go into a Command Prompt and type the following:

ASSOC .csv

This will give you a key name, such as, maybe, Excel.CSV. Use that key in the following command, for example:


This will give you the name of the executable file it tries to open your csv file with. Check that that file exists, and is not empty or a text file or any other invalid file.
