Hi, I was trying to install dcom98.exe with the latest CVS and run into several errors ranging from file-not-found errors upto problems with getting the free diskspace of drives. Tracing showed (amongst others): trace:file:GetLongPathNameW L"E:\\TOOLS",0x406cf144,1024 trace:file:RtlDosPathNameToNtPathName_U (L"E:\\TOOLS",0x406cde4c,0x406cde54,(nil)) trace:file:RtlGetFullPathName_U (L"E:\\TOOLS" 520 0x406cdc08 0x406cde54) trace:file:RtlDosPathNameToNtPathName_U At the end, returning TRUE trace:file:GetLongPathNameW not found L"E:\\TOOLS"! so we didn't get an handle from RtlDosPathNameToNtPathName_U ! After some extra tracing I decided to revert some patches and got this installation working after reverting the following patches: http://cvs.winehq.org/cvsweb/wine/dlls/kernel/volume.c.diff?r1=1.7&r2=1.8 log : Reimplemented GetDiskFreeSpaceW and GetDiskFreeSpaceExW http://cvs.winehq.org/cvsweb/wine/dlls/kernel/change.c.diff?r1=1.4&r2=1.5 log : Make FindFirstFileExW and FindFirstChangeNotificationW use NtOpenFile directly http://cvs.winehq.org/cvsweb/wine/files/drive.c.diff?r1=1.114&r2=1.115 log : Reimplemented GetDiskFreeSpaceW and GetDiskFreeSpaceExW I will investigate further, but just to let you know. I didn't try other programs. Everything done on a clean non-windows installation. Cheers, Paul.
