About the Demo
This page offers a free download of the RelCalc for Windows V5.5-217F2 Demo Package.

The Demo version is virtually identical to the full RelCalc for Windows software program and allows you to interactively try every function of RelCalc. The Demo Notes provide a step by step demo/tutorial of the RelCalc program: in about an hour you not only discover the ease of reliability prediction with RelCalc for Windows, but you have become an expert on the program, and you're ready to get right to work when you buy the full version!

Personal Engineering and Instrumentation News magazine reviewed our Demo Package a few years ago, and had this to say: "Demo packages should always be this complete, informative and easy to use. ... Even if you've never done this type of analysis before, this demo shows you what's involved in an easy-to-follow fashion. ... In summary, the RelCalc demo is very informative and easy to use. Anyone who performs reliability analysis should pick up a copy."
