With the help of FindExecutable Windows API we can trace whether a particular exe is present in the system. It will return a result depending on the handle of the executable associated with the file provided as parameter. It returns a value greater than 32 when successfull.
Lets say for example , we pass a PDF file as parameter , we can check whether Adobe Reader is installed on the system or not.

Dim intRetval As Integer = FindExecutable(PDF FILE FULL PATH NAME, "", "")
If intRetval < = 32
MessageBox.Show("The Adobe Reader, which is required to view this file, may not be correctly installed.", "Adobe Reader Not found", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
