No executable to run OpenCascade

I installed OpenCascade on Windows 7 using installation file from but after the (full) installation I don't see any executable to actually run the software... The content of my OpenCASCADE6.5.1 directory is:
Folders: 3rdparty, data, doc, ros, samples
Files: LICENSE, unins000.dat, unin000.exe
Any idea what's going on? I wouldn't be suprised to learn it's something silly on my side, but I just don't see what could it be.
I tried removing the software and installing it again with freshly downloaded wizard three times, same story each time.

OpenCASCADE is not a program, it's a set of libraries to write your own programs.

Oh my, so I indeed was silly. Then any insight on how long would it take a guy with good grasp of programming to get it up and running to make a CAD with it? I know that's not a well defined questions, but would it be an order of days, weeks, months?

Dear Jakub,
I would suggested you
1) open a documentation file %OpenCasCade6.5.1\doc\overview\index.htm
2) pay your attention at the "Welcome to Open CASCADE Technology\Getting Started" chapter
3) try to run samples referred in "Open CASCADE Technology\Getting Started\Programming Samples\MFC" chapter.
I hope it will give you some idea what is the OCCT libs and how to work with it.

Hello Jakub,

(depending on the complexity of the CAD you're planning, of course) it would probably take months... and a lot of coffee ;)

OCCT has a rather flat learning curve, I guess (just an opinion of an average programmer).

Best bet would to be to and grab something like FreeCad or similar from sourceforge.

HeeksCad is another good choice.
