Hi Gar,
Thanks for posting your question here. I would like to kindly inform you that Microsoft FrontPage 2002 isn’t compatible with Windows 11, which is why it opens briefly and then closes. Windows 11 removed several legacy components that FrontPage depends on.
You can try running FrontPage by right‑clicking FRONTPG.EXE, opening Properties, setting Compatibility mode to Windows XP (Service Pack 3), and enabling Run as administrator, then restarting and testing again. If it still does not work, the reliable options are to run FrontPage inside a virtual machine using Windows XP or Windows 7 (via VirtualBox or VMware), or to switch to a supported alternative such as Microsoft Expression Web 4 or a modern HTML editor. You may check this link for reference: Make older apps or programs compatible with the latest version of Windows
Also, unfortunately, FrontPage has been unsupported for many years, so there’s no guaranteed fix. Hope that helps.
Let me know if you have questions, I'm here to help.
Thanks,
Jobelle C,
