Dos run the .exe file of opencv

edit

I open the official opencv website for downloading opencv ,

then i clicked on OpenCV for Windows from VERSION 3.0 BETA , then this page open

and when i click on opencv.2.4.11.exe then it start downloading , after completion of downloading dos command runs and I cannt get where my opencv folder is .

As suggested by @StevenPuttemans I cleared my browsing history but still getting this.
