MiKTeX and proTeXt ⇒ Installing ConTeXt in MiKTeX

[M.A]

Dear all,

I wanted to try ConTeXt, so I have followed the installation steps under "Option 2" in:
http://wiki.contextgarden.net/MikTeX

After following the steps, I get the following error when I run "texexec.exe":
texlua: fatal: Can't determine where the executable luatex is.

Any clue?
My MiKTeX version is 2.8, and I have already installed Ruby.

Regards

Note that I have found "luatex.exe" separately, but I don't know where to place it!

I tried the Minimal ConTeXt (independent from MiKTeX) as in:
http://wiki.contextgarden.net/ConTeXt_Minimals
After completing the installation and when I run "texexec.exe" I get the following error:
mtxrun:9289: attempt to concatenate local 'v' (a table value)

They were discussing the same problem here but for UNIX:

Any help for windows ?
