Run ngen.exe after Inno install finishes but, before user can launch the app

I am able to run the following in the cmd console and it works. I can see the difference when the app is loading and when executing task within.

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\ngen.exe install "C:\Program Files (x86)\App Directroy\App.exe"

I am trying to have Inno perform the same when installing the app but, before the user has an opportunity to launch the app for the first time.

This is what I have tried so far with Inno:

[Run]
Filename: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\ngen.exe; Parameters: "install ""{app}\{#MyAppExeName}""";
Filename: "{app}\{#MyAppExeName}"; Description: "{cm:LaunchProgram,{#StringChange(MyAppName, '&', '&&')}}"; Flags: nowait postinstall skipifsilent"

What happens is that, when Inno finishes installing it starts the app and doesn't execute the ngen.

I am trying to find how to run the above code in the Inno script.

Am I placing the code in the correct section of the Inno script?

Any assistance is appreciated.

Regards,

  • I read what Martin Prikryl said about the hard-coded c:\windows... and looked into it and I found this article from Fabrizio Stellato and I was able to get it to work.

    I changed this part:

    [Run]
Filename: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\ngen.exe; Parameters: "install ""{app}\{#MyAppExeName}""";

    to

    [Run]
Filename: "{win}\Microsoft.NET\Framework64\v4.0.30319\ngen.exe"; Parameters: "install ""{app}\{#MyAppExeName}"" /nologo"; WorkingDir: "{app}"; Flags: runhidden; StatusMsg: "Optimizing..."; Check: IsWin64

    I added the {win} to replace the hard coded c:\windows

    I hid the cmd console with Flags: runhidden;

    Show the status to the user with StatusMsg: "Optimizing...";

    Fabrizio Stellato has a complete solution:

    Part 1 InnoSetup, optimize your application with ngen
