vista 16 bit applications

Which versions of Vista (if any) will support legacy 16 bit apps ?
Thanks

No guarantees but it would likely be 32-bit Vista, you probably have to run in that legacy app in compatibility mode. Windows Vista 64-bit does not have a 16-bit subsystem, so not support there defnitely. -- -- Andre Windows Connect | http://www.windowsconnected.com Extended64 | http://www.extended64.com Blog | http://www.extended64.com/blogs/andre http://spaces.msn.com/members/adacosta

Andre,
I installed the CTP on a PIII based CPU (1 GHz 513Mb RAM), so definately 32 bit and I get "NTVDM encontered a Hard Error". If I set the compatibility to Windows 95, Windows 98 or Windows XP it does exactly the same thing.
Is this a peculiarity of the app or is it that Vista does not support 16 bit apps ?
Thanks
Iain

Its probably the application, you are best running that application in a Virtual Machine. -- -- Andre Windows Connect | http://www.windowsconnected.com Extended64 | http://www.extended64.com Blog | http://www.extended64.com/blogs/andre http://spaces.msn.com/members/adacosta

Is this the only error message that you receive or are there any more after that? Have you installed your 16-bit app or just copied exe and run it? Maybe some 16-bit DLL-s are missing ...

As Andre says, 64-bit editions of Vista will NOT support 16-bit applications - they're just not designed to. 32-bit editions of Vista will support 16-bit software.
