url: "@Url.Action("GenerateReport", "ClientAdmin")",
type: "POST",
data: { reportStart: reportStart, reportEnd: reportEnd},
dataType: "json",
traditional: true,
success: function (downloadUrl) {
    //Download excel file
    window.location = "/ClientAdmin/Download?file=" + downloadUrl;
    //Delete excel file
    $.ajax({
        url: "@Url.Action("DeleteReportFile", "ClientAdmin")",
        type: "POST",
        data: { file: downloadUrl },
        dataType: "json",
        success: function (downloadUrl) {
        },
        error: function () {
            AlertShow("Error!", "Oops! An error occured");
        }
    })

I think you need jQuery "when".

http://api.jquery.com/jQuery.when/

$.when( $.ajax( "test.aspx" ) ).then(function( data, textStatus, jqXHR ) {
  alert( jqXHR.status ); // Alerts 200
});

this is to force something to be synchronous. (One can find the credited answer here)

EDIT

as I am not sure how to test your case I might suggest another solution. Try handling "file downloaded" event somehow and then trigger the delete function. Here is a possible useful answer and blog.
