I'm writing a text to speech app. It runs fine in my developer (VS 2022 vb.net) After building an install package
and installing it on my system (win 10) I get this error.

System.IO.FileNotFoundException: Could not load file or assembly 'System.Speech, Version=8.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.
File name: 'System.Speech, Version=8.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'


Question is where is it missing from?. My desktop windows system or in the installed application? When I look into the installer (Advanced Insatller 21.4) it shows the system.speech.dll in the target machines files.

Any Help would be appreciate

Thanks
