My map EXE files are Zip Self-extracting zipfiles.
Don't select SAVE to disk. Select OPEN or Run, next
download begins, then when download is done a dialog
box will appear, select OK to extract and send map
to   "C:\Program Files\Pumpkin Studios\Warzone2100".
Thats it, Now your ready to play...

 NOTE: The default Warzone2100 folder applys to the US
and other versions. I use the latest Nortons AntiVirus
to ensure of no virus risk. I'm just Trying to make it
easy for people to let the self-extracting EXE send the
map to the default Warzone2100 folder since a lot of
people cant seem to do it manually with the zip format.
