When I run wine with WINEDEBUG=+reg, I get the following message displaying endless Code: trace:reg:NtOpenKey (0xa4,L"CLSID\\{275C23E2-3747-11D0-9FEA-00AA003F8646}",20019,0x33e270) trace:reg:NtOpenKey <- (nil) err:ole:CoGetClassObject class {275c23e2-3747-11d0-9fea-00aa003f8646} not registered trace:reg:NtOpenKey (0xa4,L"CLSID\\{275C23E2-3747-11D0-9FEA-00AA003F8646}",20019,0x33e270) trace:reg:NtOpenKey <- (nil) err:ole:CoGetClassObject class {275c23e2-3747-11d0-9fea-00aa003f8646} not registered err:ole:CoGetClassObject no class object {275c23e2-3747-11d0-9fea-00aa003f8646} could be created for context 0x3 I've created a log : Code: alex@cerebro:~$ WINEDEBUG=+reg wine /home/alex/.wine/drive_c/Program\ Files/Tap\'Touche\ 5/TTouche.exe > log 2>&1 It's very long so I'll only post the interesting part but if you want, I can upload it : Code: alex@cerebro:~$ cat log | sed '/^fix\|^err/!d' | sort -u err:ole:CoGetClassObject class {275c23e2-3747-11d0-9fea-00aa003f8646} not registered err:ole:CoGetClassObject no class object {275c23e2-3747-11d0-9fea-00aa003f8646} could be created for context 0x3 err:ole:ITypeInfo_fnInvoke did not find member id -514, flags 0x4! fixme:win:SetLayeredWindowAttributes (0x10056,0x00ffffff,0,2): stub! fixme:win:SetLayeredWindowAttributes (0x10056,0x00ffffff,113,2): stub! fixme:win:SetLayeredWindowAttributes (0x10056,0x00ffffff,127,2): stub! fixme:win:SetLayeredWindowAttributes (0x10056,0x00ffffff,141,2): stub! fixme:win:SetLayeredWindowAttributes (0x10056,0x00ffffff,170,2): stub! fixme:win:SetLayeredWindowAttributes (0x10056,0x00ffffff,198,2): stub! fixme:win:SetLayeredWindowAttributes (0x10056,0x00ffffff,212,2): stub! fixme:win:SetLayeredWindowAttributes (0x10056,0x00ffffff,226,2): stub! fixme:win:SetLayeredWindowAttributes (0x10056,0x00ffffff,255,2): stub! fixme:win:SetLayeredWindowAttributes (0x10056,0x00ffffff,28,2): stub! fixme:win:SetLayeredWindowAttributes (0x10056,0x00ffffff,42,2): stub! fixme:win:SetLayeredWindowAttributes (0x10056,0x00ffffff,56,2): stub! fixme:win:SetLayeredWindowAttributes (0x10056,0x00ffffff,85,2): stub! fixme:win:WIN_CreateWindowEx Parent is HWND_MESSAGE I can install VirtualBox with WInXP (I bet that it will working perfectly) but it's less convenient than running just one application with wine.
