Melrose, et al,
Early on, Mike had a problem installing the calculator, that everyone should know about. If the folder you download it to, and double click on the file already has a file named setup.exe, the extraction program will not overwrite that file, and will use it to execute the install. The old setup.exe points to a different program, and will attempt to install it again, instead of NukeWorker calculator. I was looking at MARSSIM programs today for a project I am working on and ran into the same problem. I would have been very puzzled had Mike not figured that problem with the calculator install. Some programs come in a zip file and you have to unzip them and then double click on setup.exe. Self extracting programs, like the calculator save you that trouble, but they extract into the same folder the exe file is in. Make sure there are no files named setup.exe in the folder you execute the install for NukeWorker calculator. If there are, either delete the one that is there, or move the calculator install file to a different. If anyone has any problems, email me and describe the problem in detail. Give your O/S, error messages, etc.
