The Web installer for Java tends to be a little bit buggy. That being the case, the offline installer package will sometimes succeed where the Web installer fails. You can download the offline installer for Windows.
If you run into problems installing Java on Windows 7 or Windows 8, try installing Java as an administrator. To do so, download the offline installer and save it to an empty folder on your hard disk. Then, right-click on the executable file and choose the Run As Administrator command from the shortcut menu.
There have been some reports of antivirus software preventing Java from being installed. If you want to see whether your antivirus is causing your problem, I recommend downloading the offline installer, updating your antivirus software, and then performing a full system scan. This will help make sure that there are no infections on your system before you disable the antivirus software.
As a simple test, open a Command Prompt window, move to the directory that is pointed to by the -vm argument in your eclipse.ini, and run the intended java.exe with the -d32 switch to test if it supports 32-bit, or -d64 to test for 64-bit support. It's often simplest to download a version of Eclipse that will work with whatever Java you already have installed.
Using JMRI requires a combination of hardware (in this case running Windows), Java software and a JMRI download for a specific version. The table below shows configurations that have been reported working - there may be other combinations that are also possible, but they have not been reported by the user community. JMRI® Release Windows Rel. Java Rel. Test release 4.x.y through 4.25.9 7, 8, 10, 11, Vista Java 1.8 ("Java 8") Production rel 4.26 7, 8, 10, 11 Java 8 or Java 11 (Recommended) Production rel 4.26 Vista Java 8 Test rel 4.27.1 7, 8, 10, 11, Vista Java 8 or Java 11 (Recommended) Test rel 4.99.x 8.1, 10, 11 Java 11 Production rel 5.0 8.1, 10, 11 Java 11 Test rel 5.x 8.1, 10, 11 Java 11 Older releases: JMRI® Release Windows Rel.

JMRI also supports an offline installation - to set up, refer to the Offline Installation section below.The JMRI project is continuously adding features, bug fixes, examples and tutorials to the release, and sonew "Test" versions appear every couple of weeks. You may find one of these has features that you really want.These are announced in the JMRI users Groups.io group. Run the JMRI installer When the JMRI download is ready, you will be asked to either save it to disk or directly run the installer. [NOTE: illustrations below are not all from the same release, but should be similar to what you see.] Installer start-up Check for a previous version It will then check to see if a previous version of JMRI exists, backup any Preference, Roster and other settings and, if necessary, uninstall the old JMRI version. You may choose to have the installer make a backup of the existing files, and provide a location on disk for this set. In some circumstances, the removal of JMRI version 2.5.1 or earlier might fail, resulting in a messageUninstaller failedIn such cases, it is necessary to download and run the following file and then re-run the installer: RemoveOldJMRIUninstallEntry.exe Choose Users If supported by your Windows version and depending on the permissions of your user, the installer may ask you to choose to install JMRI just for yourself or for all users of the computer. Choose Components The installer will now present a list of the components to be installed. This will install JMRI to the default location, place shortcuts for DecoderPro and PanelPro on the desktop and create a JMRI Start Menu folder containing shortcuts for typically used JMRI programs. If you wish to change where JMRI is installed, change the install type from 'Typical' to 'Custom (select to choose program folder)' using the drop-down menu. Choose Install Location The next screen suggests a place for the install. Choose Start Menu Folder The following screens lets you choose a place for JMRI in your Start menu. Check for Java The installer will check for a suitable version of Java on your computer and, if required, will alert you to which version of Java should be installed. For example, although these messages may change based on the version of JMRI you are attempting to install. See the tables above for information about which Java is currently recommended for your version of JMRI and see the JMRI Java Recommendations page for information about downloading Java. Install files Once existence of a suitable Java Runtime Environment has been confirmed, it will then install the needed libraries, plus add a "JMRI" program group to your Start menu and put shortcuts to the DecoderPro and PanelPro programs on your desktop. Click Next. Installation is complete Using a specific java version To use a specific java installation either install that version to the JMRI install directory \jre or link the specific java version to the JMRI install directory \jre
Disco runs locally and can be used completely offline. You can set up an internet connection (also via a proxy - see Bringing Disco Online) for convenience, because it enables the automatic download and installation of new versions of the software and it allows you to send bug reports and feedback right from within the application - but this is optional. 2b1af7f3a8
