I use Linux on my home computer, and Windows on my work computer (begrudgingly).
Windows 11 does not feel like an 'upgrade' at all. One obvious downgrade is that when I try to change the settings when printing a document, the settings window does not fit on the screen. ... I don't blame Windows for that - its a big settings Window. But the issue is that Windows doesn't allow me resize it, or scroll down on it, or even let me drag it partially of the screen. And so the result is that it is impossible for me to click the 'ok' button when I'm done. The only way to save my changes is if I memorise which button is ok, then press 'tab' the exact right number of times to have it select the ok button while I can't see it, and then press enter. That's pretty crap. I didn't have that problem on windows 10. (To be honest I don't remember exactly what was different. Certainly the window with all the settings was the same, but I believe it had a scroll bar, maybe? In any case, I could certainly press the ok button before 'upgrading'!)
There are so many annoying features in Windows 11 that I've spent ages trying to turn off. For example, I was happy with the way windows could be snapped to the top and to the sides of the screen in windows 10. In Windows 11 they've expanded that feature, but made it worse. The snapping brings up menus, and behaves different ways at different times. It's fiddly and harder to predict. It tries to do more, but ends up being less useful because it is unreliable. I've disabled most of the differences in the settings, but not all can be disabled.
And there are heaps of weird inconsistencies in Windows 11. For example, when I rename a file in file explore; often stays in the same places even though it is no longer in the correct file order with the new name. So with alphabetically ordered files, there are often a few things that are out of order - because Windows is inconsistent. (Closing and reopening reorders them.) There are also some weird glitches. For example, I often see graphical glitches while using Excel in Windows 11 which I never saw in Windows 10. Things like rows partially overlapping other rows after scrolling, or the outline of the selected cell sometimes not being visible in parts of the document until you minimise and restore the app. It's pretty bogus. Obviously they've tried to change some backend stuff and created some bugs in the process.
Anyway, the point is that it easy to see why someone would be reluctant to 'upgrade' to Windows 11.
I believe that Heroic Launcher is good and trustworthy, but nevertheless I don't particularly want to be giving my GOG details to a third party. And in general, I prefer things to be simple and isolated. So I don't really want integration with different accounts anyway. I'd prefer to just say "this is the thing I want to install, and this is where I want it to be installed".
It might be possible to use Heroic Launcher in a way that would suit me, but the one time I did try to install a game with it, it didn't work and I wasn't sure where it had tried to install it, or why it didn't work... and so I basically just went back to what I was doing in the first place - which was installing games in Bottles. (And although I've spent ages trying to work out this particular problem, the fact is that I can still play every windows game I have with Bottles, including this new one.)
[edit] I feel like a lot of the replies past this point kind of ignore what I've just said. The short of it is that I'm not intending to use Heroic in the near future. I understand and appreciate that many people think its a great product. But different people have different priorities and values. I have my reasons for not using it, and the testimonials don't really address the topic of this thread. Note: the main goal of the thread is 'how can understand and fix this bottle problem', rather than 'how can I get this game working'. I can already get the game working.
