I have the same issue and it’s extremely frustrating. I cannot run HX one librarian, Line 6, Central and when I run the Line 6 updater it is just a blank page with nothing shown. I am signed in and I have tried everything that Line 6 has offered and others have offered With no luck.
I’m running Windows 11
and I have been over the owners manual more times than I can count.
Is there a mode that you have to put the pedal in? If so, I cannot find that out. I have also watched a few of the YouTube videos on updating but if you can’t load the app, the videos are useless.
I have tried different ways to remedy the problem and I have tried the same fixes over and over. One of the suggestions is to write click then go to properties then to compatibility and uncheck run this program as an administrator. The trouble is, it’s not checked in the first place. So I have tried to check it close it try the app but still the same horrible results. If only Line 6 would pay attention to this problem because I see others have the same issue. I have also tried to do the same in the root with no luck.
Kind of makes me want to throw this thing out a window. Please help.
