Glad to hear that it works for others. I had been using the same version/install for 6 - 8 monthis regularly without any problems. It just failed to launch one day. No recent java updates. I did an uninstall / reinstall last week, clearing anything I could find in the registry and disk. It still failed to start.... splash screen flashes for no more than 1 second. I did find that it launched successfully under 'Run as administrator'. I tried again this morning (same install) and it still fails, even running under admin. Thanks again for your post. Re: SoapUI 5.2.1 5.4.0 fails to start, install, unistall Hi, I am having exactly the same issue with the Open Source version of SoapUI. I would be grateful for any details on your solution that you can manage to post... Thanks.
