安裝後，有很多例子可以參考。

如下所示：

[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={pf}\My Program
; Since no icons will be created in "{group}", we don't need the wizard
; to ask for a Start Menu folder name:
DisableProgramGroupPage=yes
UninstallDisplayIcon={app}\MyProg.exe
Compression=lzma2
SolidCompression=yes
OutputDir=userdocs:Inno Setup Examples Output

[Files]
Source: "MyProg.exe"; DestDir: "{app}"
Source: "MyProg.chm"; DestDir: "{app}"
Source: "Readme.txt"; DestDir: "{app}"; Flags: isreadme

[Icons]
Name: "{commonprograms}\My Program"; Filename: "{app}\MyProg.exe"
Name: "{commondesktop}\My Program"; Filename: "{app}\MyProg.exe"

上述code中，MyProg.exe是可執行檔案；MyProg.chm是幫助文件；Readme.txt是readme。
