We are sorry for the inconvenience." My installation is completely fresh, using Wine 6.23 and Pop!_OS 21.10. No changes have been made to the default Wine installation, since I was unable to find much information surrounding this error I have only tried to change the Windows Version to Windows XP using winecfg (with no luck or change). The game properly works when running it in Windows XP. Some game info found here: https://en.wikipedia.org/wiki/Backpacker_(video_game_series) Thank you! -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 47785] New: CERT_CHAIN_POLICY_IGNORE_NOT_TIME_VALID_FLAG not taken into account
by WineHQ Bugzilla Aug. 21, 2026

Aug. 21, 2026

https://bugs.winehq.org/show_bug.cgi?id=47785 Bug ID: 47785 Summary: CERT_CHAIN_POLICY_IGNORE_NOT_TIME_VALID_FLAG not taken into account Product: Wine Version: 4.16 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: crypt32 Assignee: wine-bugs(a)winehq.org Reporter: lois.diqual(a)gmail.com Distribution: --- Created attachment 65274 --> https://bugs.winehq.org/attachment.cgi?id=65274 c# program that verifies an expired certificate using IgnoreNotTimeValid I am debugging a C# program that validates a certificate chain using X509VerificationFlags.IgnoreNotTimeValid. The provided certificate is expired, but it shouldn't matter because of this flag. The chain validates properly on MacOS with Mono. However on Wine with dotnet472, the policy fails with error NotTimeValid. I believe there is a bug in `chain.c verify_base_policy`: https://github.com/wine-mirror/wine/blob/e6138a52a907fe4b9b03abe0b6cf6cfb9f…. In this if statement, the policy verification routine determines that the certificate has expired, but it should ignore the error if `checks` contains `CERT_CHAIN_POLICY_IGNORE_NOT_TIME_VALID_FLAG`, and this logic is missing. To reproduce: - Create a wine prefix with dotnet472 using winetricks - Go to drive_c/windows/Microsoft.NET/Framework/v4.0.30319 and copy verify.cs in there - Compile verify.cs: wine csc.exe /reference:"C:\windows/Microsoft.NET/Framework/v4.0.30319/WPF/WindowsBase.dll" verify.cs - Run: wine verify.exe - It should print "Valid cert" but instead prints "Invalid cert" with NotTimeValid. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 49837] New: Just Grandma and Me (win16) softlock. Win16Mutex wait timed out

https://bugs.winehq.org/show_bug.cgi?id=49837 Bug ID: 49837 Summary: Just Grandma and Me (win16) softlock. Win16Mutex wait timed out Product: Wine Version: 5.16 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: besentv(a)gmail.com Distribution: --- Created attachment 68176 --> https://bugs.winehq.org/attachment.cgi?id=68176 Console output when running the game. I try to run the game JustGrandmaAndMe from 1997 (Version 2.0) in Wine Staging 5.16-1. Using a clean Wineprefix set to Winearch=win32 and Windows-Version 98 I ran the game's "jgmd.exe" with (put into a bashscript): WINEARCH="win32" WINEPREFIX="/home/nutzer1/Dokumente/JGM/" WINEDEBUG=warn+all wine "/home/nutzer1/Dokumente/LIVING_BOOKS/jgmd.exe" (it doesn't work in a clean ~/.wine as well) This gave me the error: err:dosmem:setup_dos_mem Cannot use first megabyte for DOS address space, please report Looking it up I found you can circumvent this error by doing: sudo sysctl -w vm.mmap_min_addr=0 But now I'm getting the error: 00b8:err:ntdll:RtlpWaitForCriticalSection section 6BB42940 "../../../wine/dlls/krnl386.exe16/syslevel.c: Win16Mutex" wait timed out in thread 00b8, blocked by 00bc, retrying (60 sec) The retries are infinite, thus causing a softlock. There are multiple bug reports with the same issue already. Overall it seems to me that the issue was fixed before but somehow reappeared.

[Bug 56565] New: Command and Conquer 3 Tiberium Wars installer crashes
by WineHQ Bugzilla Aug. 21, 2026

Aug. 21, 2026

https://bugs.winehq.org/show_bug.cgi?id=56565 Bug ID: 56565 Summary: Command and Conquer 3 Tiberium Wars installer crashes Product: Wine Version: 9.6 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: hibbsncc1701(a)gmail.com Distribution: --- Split from bug #53561. This bug is about a crash / hang in the installer for the retail release of Command and Conquer 3 Tiberium Wars when used with the recommended installation type. (The advanced installation type is unusable under Wine, see the original bug #53561.) After clicking on the next button on the installation type screen, installer appears to try and copy files. This is supposed to have a progress indicator that fills up, but it gets drawn in wine as completely full, with status "Copying new files". The UI has stopped updating and placing another window (Wine or from the host's WM) over it will cause graphical corruption. After about a minute on my machine, the UI window disappears entirely. The msiexec process however is still running in the background, and can be seen on the task bar if wine is running with a virtual desktop. It is also still visible in wine's taskmgr.exe. Where it shows two msiexec processes and one unnamed 32bit process. (Wine's taskmgr shows "*32" for the process name.) After this the process does not exit unless killed. Doing so kills both msiexec processes and the unnamed 32bit process. Looking through the registry after killing the installer, we find that it did create the needed registry keys expected by the game, in addition to installing the games files at the expected default location. The game does run in this state. So it appears that the installation was successful, despite the bug. Running the installer with WINEDEBUG="+msi" causes the installer to run correctly. I.e. It doesn't crash / hang indefinitely. Although, the UI still stops updating while the files are copied, it will recover in this case and allow the installer to run to completion. With the user able to exit the installer normally. WINEDEBUG="+msi" log attached. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
