Thanks, OPM can now see packages. I have to report that trying to install CeosMW, ExControls, ExDatabase, ExDesign, JvDesign, UserControl and EvsSimpleGraph can not succeed because those files do not exist in opm.zip. Also OpenGPSX depends on sdposeriallaz so after confirming that I want OPM to resolve this dependency OPM says it can not be found either. If I want to install only single package SDPO manually then nothing happens - not even an error. Like Install is a dead button. When I select some other package it works. All on WinXP SP3.
