I need to investigate this issue little bit if you're a Windows 10 user. However if you're familiar with regedit, please check Mudfish Launcher isn't working document about how Mudfish Launcher checks its default browser.

Hi loxch, thanks for the response. I am on Windows 10 and currently Mudfish is launching using Windows Edge instead of my default browser Google Chrome. The reason this is a problem for me is that the Final Fantasy XIV launcher is somehow linked with Edge, and when anything changes with Edge or Internet Explorer, the FFXIV launcher will malfunction and not launch. Unfortunately, I don't know enough about regedit to find the document that you're referencing.

Interesting... Because Mudfish Launcher doesn't affect behaviour of browsers, even if it opens at Windows Edge or Internet Explorer it should not affect behaviour of Fanal Fantasy XIV launcher. For a workaround, please try to use `-B` option. For details,

1. Check MUDEC_00045 error code workaround about how to set `-I` option for Mudfish Launcher.

2. Instead of `-I` option, you can place it with `-B` option.

When `-B` option is enabled, Mudfish Launcher doesn't open the default browser at all. So it means you can manually open Chrome then access to http://127.0.0.1:8282

Excellent, that worked! Now I'm able to open Mudfish using Chrome. Thanks Loxch!

Good to hear it's working for you. :-) If there are any issues, please let me know.
