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 match 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}

Solution 1:

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}

Solution 2:

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);

Solution 3:

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>
