--- Comment #3 from Pekka Helenius fincer89@hotmail.com --- I didn't do a clean bisect testing but I still have something useful for further analysis, anyway.
----------------------
Further testing indicates that launching ROTTR.exe actually fails on all tested Vanilla Wine versions (starting from 1.9.X -> 2.3 -> 2.15 -> ...).
----------------------
After a comprehensive testing, I have identified the Staging patch file which makes it possible to launch ROTTR.exe main launcher window on the newest Wine Staging Git:
-> ntdll-User_Shared_Data -> 0003-ntdll-Create-thread-to-update-user_shared_data-time-.patch
I exclusively compiled Wine Git with only the minimal required patchsets from Wine Staging in order to identify the key patch file which fixes the issue.
I ran this test multiple times (by disabling & enabling the patch file in question), and the result is reproducible.
----------------------
A) Used Staging patchsets for Wine Git:
ntdll-ThreadTime ntdll-Hide_Wine_Exports
B) And used Staging patch files (from patchset ntdll-User_Shared_Data):
0001-ntdll-Move-code-to-update-user-shared-data-into-a-se.patch 0002-ntoskrnl-Update-USER_SHARED_DATA-before-accessing-me.patch
-----
A) These patchsets are used because they are set as dependencies for the patchset 'ntdll-User_Shared_Data'.
B) Separate patch files mentioned above are a part of the patchset 'ntdll-User_Shared_Data'
