Re: Vista support for legacy applications

Thank you all for your responses, especailly Ronnie for the detailed response.

Of course Paradox is not listed in the obsolete products since it wasn't
made by Microsoft. Paradox 9 is a Paradox for Windows version, which will not
run Paradox for DOS code.

Please correct me if I am wrong: I thought Compatibility Mode was only for
16-bit WINDOWS apps.

The Microsoft position for DOS applications would follow the support for the
operating system that the applications were designed for. The support
lifecycle for the last version of DOS that I can find ended on 12/31/2001.

Obsolete Products.

It's up to the author of the application to keep pace with the current state
of hardware and operating systems. I see some information for Paradox that
mentions a version 11. There is some good information on this page:

Paradox Community.

There are many DOS based programs that were able to run in Windows XP. I
would follow Kerry's advice and try running the application on the latest
version of the Vista beta.

There is also the Compatibility Mode that can be used for Windows versions
all the way back to Windows 95. This compatibility mode option is also
available in Windows Vista.

Windows Vista CTP.

Just as an aside. One of the biggest complaints from Windows users, over the
years, has been the bloat in just about every version of Windows. One of the
main causes of the bloat is the support for legacy applications. At some
point, just about every program becomes obsolete.

What I want is Microsoft's OFFICIAL position on DOS applications.

Install it on a test computer and test your application. This is what the
CPP program is for. Read the disclaimer carefully. Do not install Vista
RC1
on a production computer. It is a Beta program Only install it on a

that you don't mind losing everything that is on the computer.

I have wasted HOURS trying to find the answer to this question;
hoping this is the place.
I need to know if Vista will run DOS applications, specifically
Paradox for DOS v. 4.0.

I am in the unfortunate position of having to support and maintain a
large amount of legacy code for PdoxDOS and it is not humanly
possible to port it all to something modern (or at least less
obsolete) by the time all new computers start shipping with Vista
preinstalled.
