TCC has no special control over running 16-bit apps; that's up to Windows 7.
Whether an app will run or not is strictly up to the Windows CreateProcess
API.

I don't have a 16-bit DOS app to try on my Windows 7 x64 system, but I doubt
an x64 version of Windows would be friendly to a 16-bit DOS app. I'd
recommend creating a VM and running the apps there.

Rex:

Would you like a 16-bit app emailled to you?

No x64 versions of Windows support running 16-bit apps, as they do not have the NTVDM subsystem.

This also saved MS from having to fix the 17 year old bug that was found recently in that subsystem. :)

Thanks Rex. I'll follow up more with DOSBox. It claims to run DOS apps under Vista & W7 32 & 64 bit, but doesn't specifically say 16 but.

Regards & thanks for the reply.

Hi,
As of DOSBox 0.73, it does not work with TCC;

http://www.jpsoft.com/forums/showthread.php?t=1620

DOSBox 0.73 has no problems running any 16-bit application, including Windows 3.1

DOSBox 0.73 is a 32-bit app, which will run on Windows 7.

With the HX DOS Extender installed in DOSBox, you can run 32-bit console applications from within DOSBox 0.73
