We are aware that the version of PowerMarker available from this site is nonfunctional, giving a message that it has expired. We are trying to find a copy of the original source code to recompile PowerMarker, but we are not very hopeful about that. Even though it remains widely used, we have not supported or updated PowerMarker for over 10 years. At this point the only way to run the software is by changing your computer.s calendar date. Please watch the web site for a message announcing either a revised download or the end of PowerMarker.
