I use OTAClient.dll from HP for conencting with Quality Center. My connection is correct:
TDConnection tdCon = new TDConnection();
tdCon.InitConnectionEx("http://....");
tdCon.Login("username", "userpass");
tdCon.Connect("****", "********");
But in this area i get error:
Req newReq = new Req();
I set platform target in x86 but didn't help me
