| Issue | Description and Solutions | | :--- | :--- | | | This classic error occurs when the software can't find its bundled Java environment. Solution: Ensure you installed CD0 first and that you used InstallLauncher.bat and not a different .exe file. Try launching directly from C:\Program Files\Dialogys\data\Dialogys.EXE . A full, clean reinstall is often the most reliable fix. | | Dialogys hangs on a logo window at startup | The program opens but freezes on the initial splash screen. This is a known issue, especially on Windows 10 and 11. Solution 1: Hold down Ctrl + Shift on your keyboard while launching the shortcut. Keep them held until a message appears confirming the registry settings have been cleared. Solution 2: Ensure your data DVDs (dvd1-7) were all installed correctly. | | Installation fails or is interrupted | Several factors can cause this. Solutions: 1) Verify you are running every InstallLauncher.bat as administrator. 2) Completely disable your antivirus and firewall before starting the install. 3) A previous failed install may have left corrupt files; use a tool like Revo Uninstaller to perform a clean uninstall before trying again. | | "Java not found" or PDFs won't open | These errors indicate missing prerequisites. Solutions: Go back and install Java JRE (version 8 works well) and a full version of Adobe Reader (not just the browser plugin). Reboot your PC and try launching Dialogys again. |
