Using Startup folder for automatic startup of application

[sonnichjensen]

I am making an installer, which should automatically start an application when Windows starts.
This can be done by adding it to the StartUp folder in Windows ( folder in C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp if not under personalised )

All this compiles, and renaming the "StartUp" will cause it not to compile.
However when I run it, it does not create the autorun that I want.

How can I achieve this?

There is
My code:

In Wix I can add those folders for shortcuts.

      <Directory Id="DesktopFolder" SourceName="Desktop" />
      <Directory Id="StartUpFolder" SourceName="StartUp" />

and the shortcut itself

      <Shortcut
        Id="StartUpShortcut"
        Directory="StartUpFolder"
        Name="$(var.ShortProductName)"
        WorkingDirectory="ProgramFilesFolder_blahblah"
        Target="[ProgramFilesFolder_blahblah]$(var.project.TargetFileName) /autorun"
        Advertise="no"
        Icon="myIcon.exe"
        IconIndex ="0"/>

I would use the run registry key for this https://docs.microsoft.com/en-us/windows/win32/setupapi/run-and-runonce-registry-keys

But its not clear from your code how you are specifying the folder for the shortcut.
Run the msi with logging to see where it is placing the shortcut.

Thanks
It seems to be the best option.
Now I found, that some policies on Win10+ will no allow this at all. But the registry will work
