To Marc & Dave, After spending 30+ years as a IBM business computer programmer & then almost 10 years working with IBM rack mounted servers, my references to the registry entries I was finding is my way to try & help with my problem.? That is the reason for running CrudCleaner to find those unattached registry entries & get rid of them.? What I did not do was to run RegEdit to "find" all the JMRI references still left after running CrudCleaner.? The references?I found last night was after an install of 4.17.6 after uninstalling 4.16.? What i am drawing a blank is how I did the uninstall.? For programs I use the Start || Settings || Apps || Apps & Features || the icon for the program being uninstalled which in this case was JMRI. I also was looking at the authority of LaunchJMRI.exe after the install.? "Users" have only Read & Execute & Read authority.? I am generally inclined to run an important app with admin authority.? Is that a problem?? Admins & System users have full authority.? LaunchJMRI is in the same folder as the InstallTest batch file but here I probably right clicked the batch file & clicked Run as Administrator. I will continue to wonder through the logs looking for Errors or something that to me raises a question. Thanks - Dennis Munro On Mon, Dec 9, 2019 at 3:20 PM <forfoum@...> wrote: Dave, |
