http://bugs.winehq.org/show_bug.cgi?id=58905 Bug ID: 58905 Summary: Many Microsoft Store installers fail to start with System.TypeLoadException Product: Wine Version: 10.18 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: mscoree Assignee: wine-bugs(a)winehq.org Reporter: lingm+winebz(a)posteo.org Distribution: --- Created attachment 79586 --> http://bugs.winehq.org/attachment.cgi?id=79586 System.TypeLoadException error Happens with: Tiktok https://apps.microsoft.com/detail/9nh2gph4jzs4 Netflix https://apps.microsoft.com/detail/9wzdncrfj3tj Prime Video https://apps.microsoft.com/detail/9p6rc76msmmj Snapchat https://apps.microsoft.com/detail/9pf9rtkmmq69 Whatsapp https://apps.microsoft.com/detail/9nksqgp7f2nh and likely many more. You'll need to switch the user agent to pretend to be on Windows to be shown the download button labeled "Install". Otherwise the Store only shows a "Copy link" button. The error can be worked around with `winetricks dotnet48`, although the next crash due to missing Windows.Globalization.GeographicRegion follows quickly. No window even appears. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

http://bugs.winehq.org/show_bug.cgi?id=26645 Summary: PAF5 throws exception after canceling print from help viewer Product: Wine Version: 1.3.17 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: rmriches(a)ieee.org Created an attachment (id=33920) --> (http://bugs.winehq.org/attachment.cgi?id=33920) stdout/stderr showing the exception The application, Personal Ancestral File 5 (PAF5), is downloadable--with registration depending on how you get to the download page. An exception is thrown and the application basically locks up after canceling a print command from the application's help viewer. In bug #25873, Erich Hoover asked to be CCed on this new report. Steps to reproduce: 1. Start PAF5. 2. Select 'New' from the dialog (or the menu bar if you don't see a dialog). 3. Click on the yellow question mark on the right-hand end of the menu bar. This brings up the help viewer. 4. Click on 'Print'. 5. In the print dialog, click on 'Cancel'. 6. Back in the help viewer, click on a couple of chapter titles in the left-hand pane. 7. Observe that the help viewer and application have become unresponsive and that an exception has been printed to stdout/stderr. I'll try to attach the log. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

[Bug 58992] New: Launching Need for Speed Underground 2 with a full path breaks KDE X11

http://bugs.winehq.org/show_bug.cgi?id=58992 Bug ID: 58992 Summary: Launching Need for Speed Underground 2 with a full path breaks KDE X11 Product: Wine Version: 10.15 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winex11.drv Assignee: wine-bugs(a)list.winehq.org Reporter: user.pecheniok(a)gmail.com Distribution: --- I launched the game the same way I launched MW here: https://bugs.winehq.org/show_bug.cgi?id=58797#add_comment Most Wanted creates a window and hangs, you can still close it. Underground 2 on the other hand does something so that the screen goes permanently black. Rebooting the PC does not help. Still searching for a solution. Of course, this is caused by an application bug, but it doesn't leave windows unusable. I think this has to be fixed as soon as possible, as this is a pretty serious issue. (Using the system on wayland now. Maybe it affects wayland too, but don't want to check for now or at least until I find a fix for the x11 issue) -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59294] New: [Enhancement] WineExplorer enhancements
by WineHQ Bugzilla Jan. 23, 2026

http://bugs.winehq.org/show_bug.cgi?id=59294 Bug ID: 59294 Summary: [Enhancement] WineExplorer enhancements Product: Wine Version: 11.0 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: enhancement Priority: P2 Component: explorerframe Assignee: wine-bugs(a)list.winehq.org Reporter: user.pecheniok(a)gmail.com Distribution: --- Wine explorer works for what it does, but there are several enhancements I think it would benefit from: - at least the first time you open it, it loads files extremely slowly. Maybe there is a way to speed it up? - you can navigate folders using the keyboard, just like on windows. However, you wouldn't know that if you tried to use them the same way. Every time you try to go back with a backspace, the explorer makes an unhelpful noise. It works if you click on empty space in the window, but you need to do that every time you change the folder. Same with arrow up/down to select folders. - it would be convenient to be able to cut/copy/paste files at least. It is pretty inconvenient to be selecting files from within a program for example and wanting to copy something, and suddenly realising you can't do that and needing to switch to the OS' file manager. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
