Thanks for the second problem. > Excel 2003 opens fine for me. Is this from a clean wineprefix--no overrides other than riched20? If not, test in a clean wineprefix. If it still doesn't start, post console output, including the command you used to run it. > In fact Office was my first install I did after Wine installation. I think Wine is clean. With line command, I got those messages : wine home/famille/.wine/drive_c/Program\ Files/Micsoft\ Office/OFFICE11/EXCEL.EXE err:process:__wine_kernel_init boot event wait timed out fixme:win:EnumDisplayDevicesW ((null),0,0x32d6c0,0x00000000), stub! fixme:wtsapi:WTSRegisterSessionNotification Stub 0xd007e 0x00000000 fixme:storage:StorageImpl_Commit (0x176c98 5): stub fixme:font:WineEngCreateFontInstance Untranslated charset 255 fixme:font:WineEngCreateFontInstance Untranslated charset 255 fixme:font:WineEngCreateFontInstance Untranslated charset 255 fixme:font:WineEngCreateFontInstance Untranslated charset 255 Actually, Excel runs but I've the error. If I click "Ok", I can use Excel but when I use the modified files on a windows session. Those files are corrupted and Excel has to fix them. I don't know how much this corruption of the files can affect them and if I risk to lose them. After the "Ok" click, I got this as console output : fixme:wtsapi:WTSRegisterSessionNotification Stub 0x90024 0x00000000 fixme:reg:GetNativeSystemInfo (0x32fbb0) using GetSystemInfo() fixme:advapi:CheckTokenMembership ((nil) 0x18b1e0 0x32fbb8) stub! fixme:advapi:CheckTokenMembership ((nil) 0x18b1e0 0x32fbb8) stub!
