I am trying to do gpg encryption through batch file
But
I get 'A 32 bit processes cannot access modules of a 64 bit process.' exception invoking Process.Start()

What I have tried:

Here is a sample of my code
Dim gpgPath As String = System.IO.Directory.GetDirectoryRoot(AppDomain.CurrentDomain.BaseDirectory) & "ABProreports\ME_ONBOARDING\Encryption\" & Format(Date.Now, "ddMMyyyy")
Dim mFileNo As Byte = 1

Dim myProcess As New System.Diagnostics.Process
myProcess.StartInfo.WorkingDirectory = System.IO.Directory.GetDirectoryRoot(AppDomain.CurrentDomain.BaseDirectory) & "APP_SERVER\ABPro\"
myProcess.StartInfo.FileName = (gpgPath & "\Encrypt_" & mFileNo & ".bat")
myProcess.StartInfo.UseShellExecute = False
myProcess.StartInfo.RedirectStandardOutput = True
myProcess.Start()
