Windows for Workgroups 3.11 installer crashes with a general protection fault I used only disk images from here: http://ia801606.us.archive.org/zipview.php?zip=/22/items/IBM_PC_Compatibles_TOSEC_2012_04_23/IBM_PC_Compatibles_TOSEC_2012_04_23.zip When I try to install Windows for Workgroups 3.11 on either PC DOS 2000 or MS-DOS 6.22, the installer crashes after entering the graphical part with two dialogs containing: Application Error WINSETUP caused a General Protection Fault in module 0EDF:7011WINSETUP will close. Application Error WINSETUP caused a General Protection Fault in module USER.EXE at 0001:40B6. And then: Standard Mode: Bad Fault in MS-DOS Extender. Fault: 000D Stack Dump: 0000 0000 0070 Raw fault frame: EC=0000 IP=5EF7 CS=037F FL=3087 SP=FFEE SS=02DF This happens both with and without KVM. I tested with QEMU from Ubuntu 14.04 and 16.04 and recent GIT (ef8757f1fe8095a256ee617e4dbac69d3b33ae94).
