Hi, I am examining a package (for work) and am trying to work out what language it was written in. Its install directory contains .dll, .xml, .exe files and an access database, I thought it was .net but when I tried to decompile it I got an error message saying that the CLI header was missing... so no to .net then?! So what language would it be?

If you have to examine a file, how would you work out what language it was originally written in?

Many thanks, Ron
