After following the double click windows install instructions here&nbsp;[http://code.kx.com/wiki/Tutorials/Installation](http://code.kx.com/wiki/Tutorials/Installation) the cmd prompt screen simply flashes for a split second then goes away.

any thoughts on how to fix?

I would think kdb+ when it starts, it cannot find q.k and exits - unfortunately that also closes the cmd window. Did you follow the instructions to define the environment var QHOME? That should allow kdb+ to locate q.k.

Otherwise I’d suggest following the instructions for the cmd window method.

Sorry for the bother - we keep weighing up whether we should have an installer for this.

thanks
