How to set or use Launchcondition Action in Wix#

[Torchok19081986]

morning, i struggle on create msi, where i can perform launchcondition action after appsearch.
Following scenario : before Plugin starts installation, it should check if mainprogramm installed and if so, check also .exe fileversion if this not versions, comes from me , are not equals cancel installation.
i done some research

public class Program
{
    static void Main()
    {
        var project = new ManagedProject("MyProduct",
                         new Dir(@"%ProgramFiles%\My Company\My Product",
                             new File("Program.cs")));

        project.GUID = new Guid("9d84f407-58c5-485d-985d-451b21f51598");

        //custom set of standard UI dialogs
        project.ManagedUI = new ManagedUI();

        project.ManagedUI.InstallDialogs.Add<WelcomeDialog>()
                                        .Add<LicenceDialog>()
                                        .Add<SetupTypeDialog>()
                                        .Add<FeaturesDialog>()
                                        .Add<InstallDirDialog>()
                                        .Add<ProgressDialog>()
                                        .Add<ExitDialog>();

        project.ManagedUI.ModifyDialogs.Add<MaintenanceTypeDialog>()
                                       .Add<FeaturesDialog>()
                                       .Add<ProgressDialog>()
                                       .Add<ExitDialog>();

        //project.SourceBaseDir = "<input dir path>";
        //project.OutDir = "<output dir path>";
        var launchCondition = new LaunchCondition();
        launchCondition.Value = "Vesion of Installed App";
        launchCondition.Message = "Application not installed or Condition are not fulfilled.";
      
        project.LaunchConditions.Add(launchCondition); <-- ??? posiblity to Add CustomAction 

        project.BuildMsi();
    }
}

public static class CusotmActions
{
    [CustomAction]
    public static ActionResult SetLaunchCondition(Session session)
    {
        return ActionResult.Success;
    }

    [CustomAction]
    public static ActionResult RegSearch(Session session)
    {
        var appKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\application").GetValue("ProgramDir").ToString();
    
        if (string.IsNullOrEmpty(appKey))
        {
            return ActionResult.Failure;
        }
    
        session["INSTALLDIR"] = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\applicationRegs").GetValue("ProgramDir").ToString();
    
        session["APPVERSION"] = FileVersionInfo.GetVersionInfo(session["INSTALLDIR"] + "\\app.exe").FileVersion;
    
        Version version = Version.Parse(session["APPVERSION"]);
    
        if(version.Major != 1 && version.Minor != 2)
        {
            return ActionResult.Failure;
        }
    
        return ActionResult.Success;
    }
}

WixToolset v4 info : https://wixtoolset.org/docs/schema/wxs/launchconditions/

for any suggestions or code , thanks.

project.Load += ... event is scheduled before AppSearch, so you can do your checking and then either abort or allow further installation. You do not have to use LaunchConditions, that don't really allow you use anything beyond simle WiX runtime constants checking.

Load          -> When.Before, Step.AppSearch, Execute.Immediate

[Torchok19081986]

thanks for quick answer, oleg. Any idea, how add cancel installation message if conditions are not fullfilled ?
something like shell.customdesriptionerror = "Application is not installed or versions are equal fir plugin " ? This property is exists only in exitdialog.

[Torchok19081986]

found it on Load Event and just tested.

try
{
    var appKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\application").GetValue("ProgramDir").ToString();

    if (string.IsNullOrEmpty(appKey))
    {
        e.ManagedUI.Shell.CustomErrorDescription = "Programm not installed.";
        e.ManagedUI.Shell.ErrorDetected = true;
    }

    e.Session["INSTALLDIR"] = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\applicationRegs").GetValue("ProgramDir").ToString();

    e.Session["APPVERSION"] = FileVersionInfo.GetVersionInfo(e.Session["INSTALLDIR"] + "\\app.exe").FileVersion;

    Version version = Version.Parse(e.Session["APPVERSION"]);

    if (version.Major != 1 && version.Minor != 2)
    {
        e.ManagedUI.Shell.CustomErrorDescription = "Condition for Installation not fullfilled.";
        e.ManagedUI.Shell.ErrorDetected = true;
    }
}
catch(Exception ex) <--- This Exception executed.
{
    e.ManagedUI.Shell.CustomErrorDescription = "Exception " + ex.ToString();
    e.ManagedUI.Shell.ErrorDetected = true;
}

i also added extra DefaulDeferedProperty APPVERSION to

project.DefaultDeferredProperties = ",APPVERSION";

appears shomehow, only exeception , not Condition for Installation not fullfilled. Versions of exe are not 1.2, but 24.3.15.20511. Any Idea why?

also even i remove this code from Load Event - i see nullref exception and msi error 1602 in windows EventLog. Now i curious. 😵‍💫😵‍💫😵‍💫😵‍💫

[Torchok19081986]

i think i run in issue. Created new wix Sharp v3 - Custom UI Project. Wait for nuget restore and rebuild project , without changes. Msi is created, but if start it on testsystem appears

also tried on current system, work pc, same error. 😧😧😧😧

[Torchok19081986]

i checked my originall project for creation msi. i had added

public static class CustomActions
{
    [CustomAction]
    public static ActionResult SetWVToolDir(Session session)
    {
        try
        {
            //x64 - 64 Bit
            session["INSTALLDIR"] = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\app").GetValue("ModuleDir").ToString();

            string path = session["INSTALLDIR"];

            session["DIR2"] = path + @"\Extension\Addins";

            return ActionResult.Success;
        }
        catch (Exception)
        {
            return ActionResult.Failure;
        }
    }

    [CustomAction]
    public static ActionResult SetExtensionManualsDir(Session session)
    {
        session["INSTALLDIR"] = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\App").GetValue("ModuleDir").ToString();
        string path = session["INSTALLDIR"];
        session["DIR3"] = path + @"\Extension\Addins\Manuals";
        return ActionResult.Success;
    }
}

this code works for setting installdr property, but on Load Event apears nullreference Exception. Is Load Event broken or something wrong with it ?

I invistigate some research further, Looks like in Custom UI Template ResetLayout Method is broken. After i commented in each dialog this method out, now it works.

Any recent changes in Custom UI Template ?

[oleg-shilo]

add cancel installation message if conditions are not fullfilled ?

Off the top of my head, you just set result to the user-exit. you can also logg the details to the session log.

args.result = UserExit;
session.Log();

As for ResetLayout. Indeed, I think it was a fix in the latest release of the template. Ensure you are using the latest:

[Torchok19081986]

thanks, again. I just checked. VS 2022 doesnt show any Updates for WixSharp Template, i intalled latest template version on my work machine.

is this somehow related to changes in #1490 ?

[oleg-shilo]

Yes, it is related.
Unfortunately, the original defect has crippled back to the template.
Maintaining two editions WiX4 and WiX3 comes with the risks. In this case, I accidentally used the binaryId of WiX4 in the WiX3 template during the packaging.

Since it happened a second time I am converting this in the CI defect.

In the meantime please use this simple workaround that will be the essence of the future fix.
In the all void *Dialog_Load(object sender, EventArgs e) methods use this routine for initializing the image:

image.Image = Runtime.Session.GetResourceBitmap("WixSharpUI_Bmp_Dialog") ??
              Runtime.Session.GetResourceBitmap("WixUI_Bmp_Dialog");

[Torchok19081986]

morning, i tested recent, 30 min ago, workaround works. Many thanks.
