almost! the first one wasn't required. *setuptex.bat* only initializes 
the context folder sub-tree to the system. this is not necessary if 
*...**\ConTeXt\tex\texmf-win64\bin\* has been added to the system path. 
in case of TeXnicCenter it might be not necessary at all, unless 
*context.exe* doesn't call any other executable or batch files. but even 
then it would look in its own folder first. i will check that out in the 
future.

it's not that i would need any of these so i didn't bother about those 
options being deactivated in the first place anyway. but thanks for 
pointing out what those are there for.

here's the point why it works now: TeXnicCenter has a location field and 
a console command field.

this is what i entered in the compiler LOCATION field before:
F:\Sandbox\ConTeXt\tex\setuptex.bat & 
F:\Sandbox\ConTeXt\tex\texmf-win64\bin\texmfstart.exe

like you pointed out before: *setuptex.bat* is not needed and the second 
path with texmfstart.exe is for i don't know what!?! but it always used 
mkii as compiler...
anyway this is from a tutorial from the contextgarden wiki: 
http://wiki.contextgarden.net/TeXnicCenter
that's why i got frustrated. the article was last updated 2012 and 
honestly i was quiet sure that's it's up to date.

so i simply changed the compiler location to 
F:\Sandbox\ConTeXt\tex\texmf-win64\bin\context.exe
and as you also pointed out i had to tell context which file. and 
therefor is the console command field. in my quotation above there is 
the following command:

"%bm"


i didn't realize that %bm is TeXnicCenter specific to handle over the 
name of the current project to the command line. it's that easy; one 
just has to know...^^

so my location is now F:\Sandbox\ConTeXt\tex\texmf-win64\bin\context.exe
and command is                        %bm

and it finally works!!! so again Pablo thanks for taking me to this.

yes, i had \language in my document before but i also added 
\mainlanguage too now. didn't know about this one, so thanks yet again.

and you were right, i now don't have any errors or warnings anymore. but 
unfortunately now console also doesn't show the quantity of pages 
compiled anymore. i tried before with *context.exe* compiler location 
(the long described case above) but it always showed 0 pages so i 
thought nothing got compiled.^^ i didn't bother anymore and changed back 
to *texmfstart.exe*. maybe i should have checked the pdfs first. :D


so yeah, i finally got ConTeXt mkiv up and running and can't wait to 
continue learning this beast. thanks a bunch Pablo. you helped me a lot.
