How to integrate MSVC-desktop/WinCE toolchain into Qt creator without installing MSVC

hello all,
I am using Qt creator2, it works well, now i want to integrate two toolchains MSVC-desktop , WinCE into Qt Creator2, i have compiled Qt-Wince4.6.2 on another computer(virtual machine) which have installed MSVC2005 , compilation done ,and i can nmake examples successfully, my own laptop haven't installed MSVC2005, i copied all necessary file from that virtual computer to my own, and i can get all the things work in windows CMD window on my own laptop, but when i integrate this toolchain into Qt creator2, it showed "Unable to detecte MSVC version", please reference the following attached image
Attachment 5210Attachment 5211
the other image showed i can get example code compiled for WinCE in CMD window with
qmake && nmake....

I don't know why Qt creator2 can't find MSVC version, am i missing any information in window's register, or any other settings??

Could anyone help me?? appreciated in Advance...

Oh~~ sorry for my ignorance.....it's OK, just ignore "Unable to detecte MSVC version" warning....
i setup build environment for wince, and at build Steps, override make command with "nmake" instead of "jom.exe", the same to Clean steps, i don't what this "jom.exe" do here....
