I am automating dot net (windows) application using QTP10.In win2003 Server it is working fine. but same dot net (windows) application is not recognising in Window 2008 Server 64 Bit OS. for all the object it displaying as winobj only. I have installed "QTP_00644.EXE" patch and latest .net frame work "dotNetFx40_Full_setup.exe". I checked in "Tools-Options-> General-> Text recognition->First Window API then OCR." This option is enable in win2003 Server. in Win 2008 server it has selected "user only OCR" and disabled. Is that issue or any other settings need to be set after / before installing. I am sure i have selected .net add-inns. Please help me as early as possible
