Error message "Nautilus has no installed viewer capable of displaying"
 

Please, Help! I am getting this message when I try to execute a file
"Nautilus has no installed viewer capable of displaying". Please, any ideas how to solve this error?

i think nautilus, at the time the error pops up, gives the option of associating an application with it if none is available. there you can type the extension you are trying to use nautilus for, such as html, etc. most file types are already listed but no app is associated. there you can type the name of the app you wish to use, if you have one capable of displaying the file format you wish to view. for example, you could type mozilla in for the html format files. the next time you click an html file mozilla should pop up. please let me know if i am wrong. i am not on my linux box at the moment. i set mine up for my stuff a while ago, so i hope this is correct. i know under options or preferences in nautilus this is possible. i apologize if this is incorrect info.
