### Output Log

```bash
Installing Chocolatey on the local machine
The registry key for .Net 4.8 was not found or this is forced
Installing 'C:\Users\\AppData\Local\Temp\ndp48-x86-x64-allos-enu.exe' - this may take awhile with no output.
MethodInvocationException: Exception calling "Start" with "1" argument(s): "An error occurred trying to start process
'ndp48-x86-x64-allos-enu.exe' with working directory 'C:\Users\\AppData\Local\Temp'. The system cannot find the
file specified."
InvalidOperation: You cannot call a method on a null-valued expression.
WARNING: Try #1 of .NET framework install failed with exit code ''. Trying again.
```

### Additional Context

The problem is that the process start cannot find the installer executable. This seems to be caused by the change of the default value of UseShellExecute of True in PowerShell 5 to False in PowerShell 7. I would suggest setting UseShellExecute explicitly to True.

Start by reproducing the Chocolatey install command in PowerShell 7 on Windows 10 LTSC 1809 and trace the .NET Framework installer process start that reports the missing executable. Check how UseShellExecute is configured for that launch; done means the .NET Framework installer starts successfully under PowerShell 7 without the reported exception.
