Repro Steps

I'm trying to launch my app, after the installation is completed. For this, I use the follwing code in my .wxs file:

<Property Id="WixShellExecTarget" Value="[#MyApp.exe]" />
<CustomAction Id="LaunchApplication" DllEntry="WixShellExec" Impersonate="yes" BinaryRef="Wix4UtilCA_X64" />

... this does not work. In the msiexec log, I found this:

Action 17:20:32: ExitDialog. 
Action start 17:20:32: ExitDialog.
Action 17:20:32: ExitDialog. Dialog created
Action 17:20:35: LaunchApplication. 
Action start 17:20:35: LaunchApplication.
Action ended 17:20:35: LaunchApplication. Return value 3.
DEBUG: Error 2896:  Executing action LaunchApplication failed.

But if I use the following code, it works fine:

<Property Id="WixShellExecTarget" Value="[INSTALLLOCATION]MyApp.exe" />

Please take a look at the Value attribute.

... but now, I get a WIX1077 warning:

The 'WixShellExecTarget' Property contains '[INSTALLLOCATION]' in its value which is an illegal reference to another property. ...

Actual Result

I'm not sure, if [#MyApp.exe] is correct, and there is a bug somewhere, of if [INSTALLLOCATION]MyApp.exe is correct, and the warning is wrong?

Expected Result

No response

WiX doesn't use issues for support. We moved this issue to the GitHub discussions area. You might also consider asking your question on Stack Overflow.

Try using SetProperty to set the Property instead of initializing it with an embedded Property in the value. I'm a little surprised the nested property works with WixShellExecTarget but your log file doesn't look verbose so I don't know that it actually is working.
