WinHttpRequest - Certificate

Hello,

I am working with WinHttpRequest object. I cannot get the SetClientCertificate to work. What am I doing wrong?

Code:

---

    Dim TestMe As New WinHttpRequest
   
    lstrBaseURL = "https://test.testplace.com:1234"
   
    TestMe.open "GET", lstrBaseURL, False

 
  TestMe.SetClientCertificate ("LOCAL_MACHINE\Personal\Name of Cert Here")
    TestMe.SetCredentials "12345678", "PSWD", HTTPREQUEST_SETCREDENTIALS_FOR_SERVER

    TestMe.send (mstrCompleteSegment)
   
    TestMe.waitForResponse

---
