Flags:

restartreplace

When an existing file needs to be replaced, and it is in use (locked) by another running process, Setup will by default display an error message.

This flag tells Setup to instead register the file to be replaced the next time the system is restarted (by calling MoveFileEx or by creating an entry in WININIT.INI).

When this happens, the user will be prompted to restart their computer at the end of the installation process.

NOTE: This flag has no effect if the user does not have administrative privileges.

Therefore, when using this flag, it is recommended that you leave the PrivilegesRequired [Setup] section directive at the default setting of admin.

regserver

Register the DLL/OCX file.

With this flag set, Setup will call the DllRegisterServer function exported by the DLL/OCX file, and the uninstaller will call DllUnregisterServer prior to removing the file.

When used in combination with sharedfile, the DLL/OCX file will only be unregistered when the reference count reaches zero.

On a 64-bit mode install, the file is assumed to be a 64-bit image and will be registered inside a 64-bit process.

You can override this by specifying the 32bit flag.

See the Remarks at the bottom of this topic for more information.

安装前卸载之前的版本

http://stackoverflow.com/questions/2000296/innosetup-how-to-automatically-uninstall-previous-installed-version

I have used the following. I'm not sure it's the simplest way to do it but it works.

This uses {#emit SetupSetting("AppId")} which relies on the Inno Setup Preprocessor. If you don't use that, cut-and-paste your App ID in directly.

下面的代码，是Pascal Script

/////////////////////////////////////////////////////////////////////
function GetUninstallString(): String;
var
  sUnInstPath: String;
  sUnInstallString: String;
begin
  sUnInstPath := ExpandConstant('Software\Microsoft\Windows\CurrentVersion\Uninstall\{#emit SetupSetting("AppId")}_is1');
  sUnInstallString := '';
  if not RegQueryStringValue(HKLM, sUnInstPath, 'UninstallString', sUnInstallString) then
    RegQueryStringValue(HKCU, sUnInstPath, 'UninstallString', sUnInstallString);
  Result := sUnInstallString;
end;

/////////////////////////////////////////////////////////////////////
function IsUpgrade(): Boolean;
begin
  Result := (GetUninstallString() <> '');
end;

/////////////////////////////////////////////////////////////////////
function UnInstallOldVersion(): Integer;
var
  sUnInstallString: String;
  iResultCode: Integer;
begin
// Return Values:
//  - uninstall string is empty
//  - error executing the UnInstallString
//  - successfully executed the UnInstallString

  // default return value
  Result := ;

  // get the uninstall string of the old app
  sUnInstallString := GetUninstallString();
  if sUnInstallString <> '' then begin
    sUnInstallString := RemoveQuotes(sUnInstallString);
    if Exec(sUnInstallString, '/SILENT /NORESTART /SUPPRESSMSGBOXES','', SW_HIDE, ewWaitUntilTerminated, iResultCode) then
      Result :=
    else
      Result := ;
  end else
    Result := ;
end;

/////////////////////////////////////////////////////////////////////
procedure CurStepChanged(CurStep: TSetupStep);
begin
  if (CurStep=ssInstall) then
  begin
    if (IsUpgrade()) then
    begin
      UnInstallOldVersion();
    end;
  end;
end;

[UninstallRun]
Filename: "{cmd}"; Parameters: "/c rd /s /q ""{app}"""; Flags: hidewizard runhidden

Filename (Required)
The program to execute, or file/folder to open.

If Filename is not an executable (.exe or .com) or batch file (.bat or .cmd), you must use the shellexec flag on the entry. This parameter can include constants.

Parameters
Optional command line parameters for the program, which can include constants.

hidewizard
If this flag is specified, the wizard will be hidden while the program is running.

runhidden
If this flag is specified, it will launch the program in a hidden window. Never use this flag when executing a program that may prompt for user input.

cmd /c 
/C Carries out the command specified by the string and then terminates.

rd命令
命令说明：rd命令只有2个参数，分别是/s和/q。
/s参数的作用是除目录本身外，还将删除指定目录下的所有子目录和文件。用于删除目录树。如果不带这个参数就只能删除空文件夹。
/q参数的作用是安静模式，带/s删除目录树时不需要确认。

[UninstallDelete]
Name: {app}; Type: filesandordirs

Name  (Required)

Name of the file or directory to delete.

NOTE: Don't be tempted to use a wildcard here to delete all files in the {app} directory. Doing this is strongly recommend against for two reasons.

First, users usually don't appreciate having their data files they put in the application directory deleted without warning (they might only be uninstalling it because they want to move it to a different drive, for example). It's better to leave it up to the end users to manually remove them if they want.

Also, if the user happened to install the program in the wrong directory by mistake (for example, C:\WINDOWS) and then went to uninstall it there could be disastrous consequences. So again, DON'T DO THIS!

Type  (Required)

filesandordirs

Functions the same as files except it matches directory names also, and any directories matching the name are deleted including all files and subdirectories in them.

OnlyBelowVersion

http://www.jrsoftware.org/ishelp/index.php?topic=setup_onlybelowversion

Format:  major.minor

Default value:0

Description:

This directive lets you specify a minimum version of Windows that your software will not run on. Specifying "0" means there is no upper version limit. Build numbers and/or service pack levels may be included.

This directive is essentially the opposite of MinVersion.

For compatibility with previous versions of Inno Setup, separate Windows 95/98/Me and Windows NT version numbers may be specified, separated by a comma. Example: OnlyBelowVersion=0,6.0. The Windows 95/98/Me version number (the first number) isn't used, however, as Inno Setup no longer supports Windows 95/98/Me.

Windows Versions

http://www.jrsoftware.org/ishelp/index.php?topic=winvernotes

Note that there is normally no need to specify the build numbers (i.e., you may simply use "6.2" for Windows 8).
