How To Fix A General Protection Fault
when you try to run a legacy 16-bit application in Windows XP and above you will receive the GPF (General Protection Fault). The Windows 80×87 emulator library, WIN87EM.DLL, works at the 16-bit-Windows level to virtualize the coprocessor among multiple Windows-based applications that run inside the system VM. It appears to me

that, with the Virtual Machine using a Virtualized Processor (not related to the above reference to "virtualized coprocessor") as opposed to an emulated processor, the Virtual Math Coprocessor Device (VMCPD) and/or WIN87EM.DLL generate an error from the virtualized processor. So how do we fix it. Simple enough you just have to to "hiding" the math coprocessor from the Virtual Machine, so it doesn't go to the processor. This apparently can be achieved by using a program called WinFloat which includes a tool called HIDE87, which is suppose to hide the math coprocessor from the kernel. Lucky for us you can download winfloat from http://www.conradshome.com/win31/archive/. Click on winfloat.exe to download to a directory. Once downloaded double-click to extract the files. Copy HIDE87.com to c:\windows\system32 directory Add lh c:\windows\system32\HIDE87.com as the first line to the c:\windows\system32\autoexec.nt file. Reboot virtual machine The error should now be gone. This will work with virtual machines running on V

General Protection Fault Windows Xp
WIN87EM.DLL while Running Windows XP Mode Windows 7 IT Pro > Windows Virtual PC general protection fault error code and XP Mode Question 1 Sign in to vote I am attempting to run a legacy, 16-bit program, P3,on a Windows XP Mode http://lifeofageekadmin.com/fix-general-protection-fault-module-win87em-dll-running-windows-7-vmware/ Virtual Machine, hosted by a Windows 7 x64 box. When performing various activities in the program, I receive "P3 caused a General Protection Fault in module WIN87EM.DLL at 0001:02C6." This occurs on multiple platforms (Core i5, Core 2 Duo). Based on my research, I have found "The https://social.technet.microsoft.com/Forums/en-US/e0922437-0dc7-4091-a8f7-fadc7fb5bbb5/general-protection-fault-in-module-win87emdll-while-running-windows-xp-mode?forum=w7itprovirt Windows 80x87 emulator library, WIN87EM.DLL, works at the 16-bit-Windows level to virtualize the coprocessor among multiple Windows-based applications that run inside the system VM."

In addition "When the kernel loads an application, it checks to see if floating-point hardware is present. If a coprocessor is not present, the kernel uses the fixup records to replace the actual floating-point instructions with Interrupt 3x calls to emulation code in WIN87EM.DLL." I have found some information that points to "hiding" the math coprocessor from the Virtual Machine, so it doesn't go to the processor.
