For your information...

After installing ConTeXt with
ContextMinimalInstall.exe, which didn't succeed,
I took http://minimals.contextgarden.net/setup/context-setup-mswin.zip
but couldn't figure out how to configure sciTE - even after reading the
"SciTE in ConTeXt" manual several times it still was a complete mystery,
so in the end found http://www.pragma-ade.com/context/install/mswincontext.zip
which is configured for SciTE.

Is there a better alternative ?
