all files am trying to download with safari was not downloading..and a message box always says that safari cannot download this file..
Safari cannot download files. (another simple thing that apple should allow it to do) You will have to use a 3rd party browser from the AppStore.
Try iCab, this allows up and downloading. Alternatively you could try something like Downloads HD. The Archangel

.exe files are self executing windows (or DOS) files. They will not run in the iOS environment. The Archangel
