MSI installer to check file exist on client machine

Question

User-496715785 posted

I have created simple msi, now I want to check another application is installed on the client machine or not before my msi runs.

because the application what I have created has a dependency of another application. If my application has to work on the client machine then that machine should have another application installed.

Lets say a.exe has a dependency on b.exe.

I have created msi for a.exe, when I run msi for a.exe in client machine then this msi has to detect whether b.exe is isntalled in client machine or not. if not then terminate the msi isntallation

Hi baskerganesan,

You could use File.Exists Method (String) to check if a file exists.

// See if this file exists in the C:\ directory.
if (File.Exists(@"C:\b.exe"))
{
    Console.WriteLine("The file exists.");
}
