Do you know how I can open an attachment (from a well known source) that has the ext ".pub"????

A file w/ the extension .pub...That's a Microsoft Publisher file...Only Microsoft Publisher can open those. Unfortunately, that's not a free program, so try to get the same file in a PDF format. This way, you can just use Adobe to view it. Or you could spend $50 or so and get Publisher.

If the other answer didn't work then check that you have a program installed and associated with the type of attachment you want to open.\n\nEach attachment needs a certain program to open. Each file has a 3 letter extenstion which is associated to a a program on your pc if the pc has a program register for that extenstion that is. If there is no program installed to view that extenstion it won't work. Check the 3 letters at the end of the attachement (somthing.ext) where something is the filename and .ext is the extention Search  the extenstion in Yahoo and see if that helps.\n\nSome common extenstions for which you might not have a program installed\n.DOC = Microsoft word ( open office.org will open them as well)\n.PPS or PPT - MS Powerpoint\n.XLS = MS Excel\n.RAR = Winrar

you have to download a bittorrent client like utorrent, and download torrents from a torrent site like mininova,then open the torrent in utorrent

It is called "extention".\n\nSo, you need an extension list.\nOne of them (very wide) is attached. You can obtain there an alphabetically list of extensions as well as associated extentions with some program.

Thats a outlook "feature" that extracts potientially dangerous attachement files like *.exe; *.com, *.bat, *.vbs, and so on.\n\nThere are ways to circumvent that:\n- Either you turn that option (security)\n- Or you just zip the files before you send them.\n\nGo for option 2!

i believe you want HKEY_CLASSES_ROOT in regedit, it lists all the file extensions and the associated application...

Disable the Firewall and try (right click the icon by the time)\n\nAlternatively, the size of the attachment WILL cause problems if it is generally7 over 1 mb

Does the source file exist? Doesn't your firewall block downloading components?
