--- Comment #48 from Andrew Church achurch+wine@achurch.org --- (In reply to Jacek Caban from comment #45)
If any other fix is still missing, it would be interesting to know what exactly.
Unfortunately, the launcher is still broken as of 10.0-rc1. The failure state is somewhat different, as the "loading" animation (3 dots) in the lower-right corner of the launcher now animates where it did not before, but while 10.0-rc1 with dlls/{jscript,mshtml} from my branch proceeds from the splash screen to the main launcher screen in about 2 seconds, vanilla 10.0-rc1 remains stuck on the splash screen after 30 seconds, so either something is still missing or there is an extreme performance issue.
I don't see any errors from jscript or mshtml, and running with WINEDEBUG=+jscript,+mshtml adds so much logging overhead that the window itself can barely open. Do you have any other diagnostic suggestions?
