Question

is it possible to close a running application with another application?

I have implemented APP1.exe and APP1_UNIN.exe, I would that APP1_UNIN.exe kill running APP1.exe and uninstall it.
Is it possible?

Answer 1

To uninstall an application, you can start a new process and invoke msiexec.exe, and on the command line you can specify what to uninstall:

ProcessStartInfo psi;
//take your choice of which you want to use:
psi = new ProcessStartInfo("msiexec.exe", string.Format("/x {0}", "path of my msi"));
psi = new ProcessStartInfo("msiexec.exe", string.Format("/x /n {{{0}}}", "my product code"));
Process p = new Process();
p.StartInfo = psi;
p.Start();
