Win87EM.dll fault

I need to run a 16-bit application on Windows 7, without the use of VM or Windows XP mode.  This application runs well on one Windows 7 32-bit machine, and I need to run it on another machine which initially had only 64-bit Windows 7.  I changed the system disc format from GPT to MBR and installed a 32-bit Windows 7 operating system on the 64-bit machine, and it works fine.  However, the application generates a General Protection Fault in WIN87EM.DLL at address : 0001:02C9.  I tried disabling the display adapter, but that did not help.  Please advise.

There are some potential solutions in this thread.  I hope one of them may work for you

One is a Video solution and then the other is related to the computer hardware.

I hope something here will help you.

Thank you.  I have tried those fixes, before posting this question, but they didn't resolve it.

The hardware is too new for the 16-bit processes.

Can you set up DOS as a Virtual Machine within the Windows 7 32-bit machine and then network the DOS machine to the Windows 7 32-bit machine. You need the LANMAN drivers for DOS to do this.

Is WIN87EM.DLL the same on both systems?  If not, try copying the working version over to the new system.

You might also run Dependency Walker on both the working and non-working system and note any differences.
