which did not work, as the MsiServiceConfigFailureActions table does not work if using an installer < 5.0, and even if using InstallerVersion="500" the only thing I get is an error:
Serivce 'My Product' (My Product) could not be configured. This could
be a problem with the package or your permissions. Verify that you
have sufficient privileges to configure system services.
(and yes, ... I've tried InstallPrivilges="elevated" also - but ... the real issue is Action="restartService" according to this)
So ... using a CustomAction is the way to go (or not?).
I have following output of the log

Can anybody help me out?
edit
I've used the old ServiceConfig-extension:
<util:ServiceConfig xmlns:util="http://schemas.microsoft.com/wix/UtilExtension"
FirstFailureActionType="restart"
SecondFailureActionType="restart"
ThirdFailureActionType="restart"
ResetPeriodInDays="1"
RestartServiceDelayInSeconds="20" />
which gives me a following build-error:
error CNDL0200: The ServiceInstall element contains an unhandled
extension element 'util:ServiceConfig'. Please ensure that the
extension for elements in the
'http://schemas.microsoft.com/wix/UtilExtension' namespace has been
provided.
I know that I can resolve this error by using -ext WixUtilExtension via commandline - but I want to use Visual Studio for building ... So how can I adapt the build-command?
Only chance is to add a reference to WixUtilExtension.dll to my project.

I can see that you've only tried the ServiceConfig element, which came with MSI 5.0. However, there's another ServiceConfig element in UtilExtension, which has been there for a long time and it seems that the thread you mention in your question confirms that it works.
The util:ServiceConfig element contains 3 parameters you'd like to use: FirstFailureActionType, SecondFailureActionType and ThirdFailureActionType, all accepting the same enumeration of values - none, reboot, restart and runCommand.
Try it out and if it works, it is far better choice than a custom action.

For WIX V 4.0, building with VS2015, the following works:
1: Ensure that WixUtilExtension.dll assembly is referenced by WIX project.
2: Add http://wixtoolset.org/schemas/v4/wxs/util ns to root Wix element. Note that this is the correct NS for WIX 4.0 (NOT http://schemas.microsoft.com/wix/UtilExtension as for previous versions).
<Wix
xmlns="http://wixtoolset.org/schemas/v4/wxs"
xmlns:util="http://wixtoolset.org/schemas/v4/wxs/util"
>
3: Ensure that ServiceConfig element is prefixed with correct namespace reference.
<ServiceInstall
Id="MyService"
Type="ownProcess"
Name="MyService"
DisplayName="MyService"
Description="My Service"
Start="auto"
Account="[SERVICEACCOUNT]"
Password="[SERVICEPASSWORD]"
ErrorControl="normal"
>
<util:ServiceConfig
FirstFailureActionType='restart'
SecondFailureActionType='restart'
ThirdFailureActionType='restart'
RestartServiceDelayInSeconds='30'
ResetPeriodInDays='1'/>
</ServiceInstall>

In Visual Studio, to avoid using -ext in CLI you may do the following:
Of course, you add a resource: <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:util="http://schemas.microsoft.com/wix/UtilExtension">
then, in Solution Explorer -> References -> Add..
WixUtilExtension.dll
After that everything works like a charm.
(wix 3.10)
Of course, if you do use the second ServiceConfig from utils. Like <util:ServiceConfig blablabla

Each version of the .NET Runtime will create a directory in Program Files\dotnet\shared\Microsoft.NETCore.App\
The existance of the directory Program Files\dotnet\shared\Microsoft.NETCore.App\6.0.5 confirms the existance of .NET Runtime version 6.0.5. Using this knowledge, you can do a simple DirectorySearch in Wix to check whether a specific version of the runtime is installed like so:
<!-- Check if NET 6.0 Runtime already installed -->
<util:DirectorySearch
Path="[ProgramFiles6432Folder]dotnet\shared\Microsoft.NETCore.App\6.0.5"
Result="exists"
Variable="Net6RuntimeExists"/>

Upgrade to a newer version using WIX Installer doesn't copy the new files

I am trying to upgrade an already installed MSI package from V1 to V2.
The MSI package is part of a bundle (we have 10 different MSI packages in the bundle, but only this one is causing upgrade issues).
The problem I have is that after upgrade the new version appears correct in Control Panel but when I go to the disk the new files are not copied and I'm left with the old files on the disk (V1 files).
If I do a Repair from Control Panel the new files get copied with the correct version.
I am using WixSharp version 1.4.4.1.
Does anyone know why the upgrade is not done properly?
An example of how the Bundle.wxs looks like can be found below:

The MSI project is created using the following lines:
var project = new ManagedProject();
project.Name = "Test";
project.Description = "Test Package";
project.GUID = Guid.Parse("{94682162-F133-40A3-92BB-0AF08142474C}");
project.ProductId = Guid.Parse("{94682162-F133-40A3-92BB-0AF08142474C}");
project.Dirs = GetDirectoriesAndFilesToInstall();
project.Version = GetInstallerVersion();
project.BannerImage = "Banner.bmp";
project.Actions = new WixSharp.Action[]
{
new ElevatedManagedAction(CustomActions.UninstallService, Return.check, When.After, Step.InstallInitialize, Condition.Always),
new ElevatedManagedAction(CustomActions.InstallService, Return.check, When.After, Step.InstallExecute, Condition.Always),
};
project.BuildMsi(msiPath);
I found the problem: the upgrade only works if you add files during the upgrade, not if you remove files.
I compared the old installation with the new one and 6 files were missing from the new one. Because of that the upgrade didn't update any files at all.
The article that inspired me can be found here:
MSI Installer Rules
I realized that I broke Rule 2: Only add, never remove resources from a component
This is somehow weird, what if I want to remove files during an upgrade? What solutions do I have?
UPDATE: I found out that the MajorUpgrade can be forced in code like below:
var project = new ManagedProject
{
Name = "Your name",
Description = "Your description",
GUID = Guid.Parse("{94682162-F133-40A3-92BB-0AF08142474C}"),
MajorUpgrade = new MajorUpgrade
{
DowngradeErrorMessage = $"A later version of {projectName} is already installed. Setup will now exit."
},
Actions = new WixSharp.Action[]
{
new ElevatedManagedAction(CustomActions.UninstallService, Return.check, When.After, Step.InstallInitialize, Condition.Always),
new ElevatedManagedAction(CustomActions.InstallService, Return.check, When.After, Step.InstallExecute, Condition.Always),
}
};
and you don't need to change the major part in the assembly version.
For instance, if the existing installer had version 1.1.0.0 installed, then you can force a Major Upgrade in code but change the version to 1.2.0.0 instead of changing to 2.0.0.0.
Also, in the installer bundle project I had to add this property: EnableFeatureSelection="yes" for each of the MSIPackage element. This property enables you to catch the event named: DetectRelatedMsiPackage. This will help you to differentiate between versions and identify which package is installed or not and also which one can be upgraded.

Shortcut (non-advertised) not being created with Wix installer?

I built a simple MSI installer with Wix 3.11. It includes an EXE and a shortcut, but the shortcut never appears on the desktop. I build the MSI without errors, it otherwise installs just fine, and there are no errors in the MSI log file. I viewed the MSI with Orca and I see the shortcut and desktop directory in their tables. Thoughts? I've tried setting ALLUSERS to 1 as well to no avail. Here is my wxs file:

Update: when the shortcut doesn't specify and icon, I see this in the installer log:
Action start 16:27:50: CreateShortcuts.
MSI (s) (08:34) [16:27:50:522]: Note: 1: 2205 2: 3: Icon

Action ended 16:27:50: CreateShortcuts. Return value 1.
When I do specify one, I see even less:
MSI (s) (14:D0) [16:34:59:527]: Doing action: CreateShortcuts
MSI (s) (14:D0) [16:34:59:527]: Note: 1: 2205 2: 3: ActionText

Action ended 16:34:59: CreateShortcuts. Return value 1.
So, no indication of failure. The icon just goes into the ether.
I'm not sure if this is your issue but to use the desktop folder you just define it as
<Directory Id="DesktopFolder"/>
I think you are actually putting the shortcut in "C:\Desktop\" (assuming the TARGETDIR is C:). All System Folder Properties should be defined the same way.
Also, remove this from your component definitions
<RemoveFolder Id="RemoveDesktopFolder" Directory="DesktopFolder" On="uninstall"/>
You don't want to remove the Desktop folder, it's not something you created in your install and neither is it something you own. Also, RemoveFolder will not do anything if anything else is present in that folder and basically everyone has at least a Recycle Bin in their desktop folder so it will never do anything.
I'm not sure why the RemoveFolder is used in other Shortcut definitions like the startmenu. It may be due to how windows installer works where it only implicitly removes a folder if components containing Files were present.
I'm pretty sure that Target must be an ID, not the name of the file. So change
Target="ImaginaryUI.exe"
to
Target="[#ImaginaryUIEXE]"

WIX does not remove the web applications after uninstall in wix

We are using WIX 3.10 to create web applications under default website, this implementation works fine but the issue is with uninstall of the product that it does not remove the web application under the default website.
The Website port and name are entered by user as part of custom dialog which are stored in respective properties.further during uninstall these properties are restored using wix toolset remember property http://robmensching.com/blog/posts/2010/5/2/the-wix-toolsets-remember-property-pattern/ which sets the web application property during uninstall, but still the application is not removed on uninstall.
Uninstall log that sets the website properties after Appsearch:

WebAppPool fails if AppPool already exists - WiX 3.5

This was working in WiX 3.0.

Installing on Win Server 2008 R2. The AppPool already exists. If I remove the AppPool, the installer succeeds. Any thoughts? Thanks...
I would recommend you to create a customAction for creating virtual directory along with Application Pool.
I have used custom action in my project for that purpose. In the custom action you can check whether the application pool with the given name exists or not.
Added inbuilt commands
