Avoid confirmation box in MsiExec uninstall

MsiExec.exe /I{A52EEC0E-D0B7-4345-A0FF-574804C7B78A} /passive

{A52EEC0E-D0B7-4345-A0FF-574804C7B78A} --> is Product Code
 
If you want to completely hide the UI, use the /quiet (நீங்கள் முற்றிலும் UI மறைக்க விரும்பினால்)

switch instead of /passive.


Example C#

            Process p = new Process();
            p.StartInfo.FileName = "msiexec.exe";
            p.StartInfo.Arguments = "/x {A52EEC0E-D0B7-4345-A0FF-574804C7B78A} /passive";
            p.Start();

OR

            Process p = new Process();
            p.StartInfo.FileName = "msiexec.exe";
            p.StartInfo.Arguments = "/x {A52EEC0E-D0B7-4345-A0FF-574804C7B78A} /quiet";
            p.Start();

             Process p = new Process();
            p.StartInfo.FileName = "msiexec.exe";
            p.StartInfo.Arguments = "/qn /x {A52EEC0E-D0B7-4345-A0FF-574804C7B78A}";
            p.Start();
