Installation Error 1158

I am trying to re-install Draftsight on HP desktop WIN 7 Professional 64 bit after reactivation failed, downloaded the most recent version from website. Double clicked on downloaded .exe file, installation starts, click RUN when prompted then a small box pops up with a single number 1158, click to close the box and installation stops.

How to install Draftsight? Run as Administrator has yielded the same result.

Any ideas?
