Does anyone have a clue or have solved this type of problem?

My C# app is run as administrator.

I elevate run as admin for the cmd prompt as well.

Using a C# Process to run a silent ODBC 32.Bit driver install works at cmd-prompt but not within a C# process.

The command looks like this by the promp(works)t:

setup.exe -psc_s -psc_f1=C:\Users\Administrator\AppData\Local\Temp\_Progress_ODBC_32\response.ini -psc_f2=C:\Users\Administrator\AppData\Local\Temp\_Progress_ODBC_32\oesetup.log -hide_progress -hide_splash

In C# it is run by the typical

Process process = new Process();

process.StartInfo.FileName = strPathAndFilename; //path to setup.exe

process.StartInfo.Arguments = strArguments; //same arguments as by the cmd-prompt

process.StartInfo.UseShellExecute = false; //false

process.StartInfo.RedirectStandardOutput = true; //true

process.StartInfo.RedirectStandardError = true; //true

process.StartInfo.CreateNoWindow = true; //true

process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

process.StartInfo.WorkingDirectory = @"C:\Users\Administrator\AppData\Local\Temp\_Progress_ODBC_32";

process.Start();

process.WaitForExit();

When I run the same command in a c# process as by the cmd prompt it doesn't work. I get the return code -2147213312

I was told that this typically means the installer tried to perform a function that is not supported in the current context — such as trying to show a dialog box in a silent install, or relying on a UI element or interaction.
