# define the name of the installer
outfile "simple installer.exe"
 
# define the directory to install to, the desktop in this case as specified  
# by the predefined $DESKTOP variable
installDir $DESKTOP
 
# default section
section

Install a file and create an uninstaller to remove it

This script will do the following: create an installer named "installer.exe"; install a file named "test.txt" to the desktop; create an uninstaller named "uninstaller.exe" on the desktop. The uninstaller will remove itself and the installed text file.

# define installer name
outFile "installer.exe"
 
# set desktop as install directory
installDir $DESKTOP
 
# default section start
section
 
# define output path
setOutPath $INSTDIR
 
# specify file to go in output path
file test.txt
 
# define uninstaller name
writeUninstaller $INSTDIR\uninstaller.exe
 
# default section end
sectionEnd
 
# create a section to define what the uninstaller does.
# the section will always be named "Uninstall"
section "Uninstall"
 
# Always delete uninstaller first
delete $INSTDIR\uninstaller.exe
 
# now delete installed file
delete $INSTDIR\test.txt
 
sectionEnd
