I have an identical problem. Start11 was working perfectly until I paid for the recent upgrade and installed. I've reinstalled it numerous times after complete uninstalls. I kept the firewall off. NO JOY. Click on the Start11 button and nothing happens. I uninstalled the upgrade and reinstalled the earlier version and it works fine. If I can't get a solution, I'd like my money back for the upgrade. But I sure would much prefer a solution. Oh, it's Windows 11.
Sorry to hear you are having issues. Need to know more on your issue.
- Need to know your Windows 11 full version numbers, use Winver.exe to get those.
- What version of Start11 that work and what version that don't work.
- While it don't work by clicking on the start button, does it work if you press the Windows keys on your keyboard?
