How do I automatically set the version of my Inno Setup installer according to my application version?

I am using Inno Setup to generate the installer of my application. How can set the version number of the setup.exe (VersionInfoVersion) generated by Inno to m开发者_C百科atch with the version number of my application automatically? Now every time I deploy a new version of my application I need to update the version number manually.

Now I'm doing this:

[Setup]
VersionInfoVersion=1.2.2.0 //writing the value manually

I want something like this:

[Setup]
VersionInfoVersion={Get the version of my app}

You can use the Inno Setup Preprocessor GetVersionNumbersString function like this

#define ApplicationName 'Application Name'
#define ApplicationVersion GetVersionNumbersString('Application.exe')
[Setup]
AppName={#ApplicationName}
AppVerName={#ApplicationName} {#ApplicationVersion}
VersionInfoVersion={#ApplicationVersion}

Another way to do it by using a command line argument :

[Setup]           
AppVersion={#MyAppVersion}

and you just call your script as follow from a cmd :

cd C:\Program Files (x86)\Inno Setup 5

iscc /dMyAppVersion="10.0.0.1" "C:\MyPath\MyScript.iss"

It emulate #define MyAppVersion="10.0.0.1" in the iss script.

If you are using CakeBuild, you can pass this argument as

 string CurrentVersion  = "10.0.0.1";
 InnoSetupSettings settings = new InnoSetupSettings();
 settings.Defines=   new Dictionary<string, string>
            {
            { "MyAppVersion", CurrentVersion },
            };
   InnoSetup("C:\MyPath\MyScript.iss", settings);

In case you have a pure webinstaller, the accepted solution won't work, because you simply won't have an application.exe to get the version number from.

I'm using Nant and a build.xml file with version number properties, which i manually bump, before i'm rebuilding the innosetup installers.

My *.iss files contain a special token @APPVERSION@, which is replaced with the version number during the build process. This is done via a copy operation with an applied filterchain, see below.

InnoSetup Script (*.iss)

// the -APPVERSION- token is replaced during the nant build process
#define AppVersion "@APPVERSION@"

nant build.xml:

<!-- Version -->
<property name="product.Name"           value="My Software"/>
<property name="version.Major"          value="1"/>
<property name="version.Minor"          value="2"/>
<property name="version.BuildNumber"    value="3"/>
<property name="product.Version" 
          value="${version.Major}.${version.Minor}.${version.BuildNumber}"/>

<!-- build task -->
<target name="bump-version"
        description="Inserts the current version number into the InnoScript.">
        <copy todir="${dir.Build}" overwrite="true">
            <fileset basedir="${dir.Base}/innosetup/">
                <include name="product-webinstaller-w32.iss"/>
                <include name="product-webinstaller-w64.iss"/>
            </fileset>
            <filterchain>
                <replacetokens>
                    <token key="APPVERSION" value="${product.Version}"/>
                </replacetokens>
            </filterchain>
        </copy>
</target>

I had some problems with getting this to work, so just contributing my solution.

app.iss:

[Setup]
#include "Config.txt"

#define AppVersion GetFileVersion("Input\" + AppExec)


AppName={#AppName}
AppVersion={#AppVersion}

Config.txt:

#define AppName "App"
#define AppExec "App.exe"

As others have mentioned, the GetFileVersion or GetStringFileInfo preprocessor functions can be used for that.

Some important info, improvements and helpful additions:

• You can either use an absolute path to the exe, or a path relative to the .iss file
• You can include existing defines in your statement by just writing their name, and concatenate defines with the + operator:
  #define MyAppPath "..\Win32\Release\" + MyAppExeName
• If you want you can easily remove parts of the version number from the right by using the function RemoveFileExt, e. g. convert 3.1.2.0 to 3.1.2:
  #define MyAppVersion RemoveFileExt(GetFileVersion(MyAppPath))
• You can use the defines MyAppExeName and MyAppPath in the subsequent options like Messages, Files or Icons

Working example:

#define MyAppName "Application Name"
#define MyAppExeName "Application.exe"        
#define MyAppPath "..\Win32\Release\" + MyAppExeName
#define MyAppVersion RemoveFileExt(GetFileVersion(MyAppPath))

[Setup]
AppName={#MyAppName}
AppVersion={#MyAppVersion}
AppVerName={#MyAppName} {#MyAppVersion}
VersionInfoVersion={#MyAppVersion}
OutputBaseFilename={#MyAppName}-{#MyAppVersion}-Windows

...

[Messages]
SetupWindowTitle=Setup - {#MyAppName} {#MyAppVersion}

...

[Files]
Source: {#MyAppPath}; DestDir: "{app}"; Flags: ignoreversion; Tasks: desktopicon

...

[Icons]
Name: "{group}\{#MyAppName}"; Filename: "{app}\{#MyAppExeName}"

In my case, I would like to define the version string from a file. I don't have an EXE, since my installer is packing an embedded Python program. So I define the version number in a one-line text file like such (this is created from a git tag statement beforehand):

..\Build\app_version.txt:
v1.2.1

In the Inno Setup, I used a pre-processor define statement to set the version throughout the text.

#define VerFileNum FileOpen("..\Build\app_version.txt")
#define MyAppVersion Trim(StringChange(FileRead(VerFileNum),"v",""))

Here, I used Trim() and StringChange() to remove the leading "v" and trailing spaces from the string. Later in the setup section, the AppVersion value can be set using the pre-processor definition:

[Setup]
AppVersion={#MyAppVersion}

The Inno Setup pre-processor has quite an extensive set of functions already defined: Inno setup pre-processor functions

After quite some time trying other methods, the way it worked for me was to use a relative path (I have the .iss file in a folder and the EXE file two levels above).

; Extract File Version from EXE
#define MyAppVersion GetFileVersion("..\..\Release\CSClave.exe")
