converting a .dat file to a .exe file

Assuming that all that was done was a change in the file extension, here is what to do.

Save the file from the e-mail to your hard drive.

Open Windows Explorer.

Browse to the file.

Right click on the file.
Select rename.
Remove the .dat extension.
Click ok.

The file should now be setup.exe and the icon should match that of other executable files.

try using Quikview to "open" the file. if you can without getting error messages and the top line in the viewer window says WINDOWS EXECUTABLE then you know you can simply rename the .dat extension to .exe
