<DIV class=moz-cite-prefix>Hi,<BR><BR>The actual file you're referencing may
be able to be extracted using 7Zip, since it's a self-extracting archive.
However, that won't get you very far, as the programs contained within are
also 16-bit, and designed to run under DOS. You need to understand, at the
time these files were released, Windows 9X at the very latest was the most
modern consumer operating system available, and that ran on top of DOS. Also,
probably many computers with DECtalk Express units didn't have Windows
installed at all, and ran pure DOS, with DOS applications exclusively.
Therefore, it was taken for granted that any PC user with a DECtalk Express
would have no problem running DOS applications. As far as I know, there has
never been any Windows software which can upgrade or downgrade DECtalk Express
firmware, it has to be done from DOS.<BR><BR>While you may be able to get a
virtual machine going, whether it can access a USB serial port is beyond me.
What I'd do in your situation is to find a 16-bit DOS or 32-bit Windows
machine and upgrade the firmware from there. If you're using a DOS prompt from
within Windows, you need to make sure nothing else is trying to access the
serial port while the firmware upgrade is happening. To be really safe, use
Windows 95 or 98, which allow you to exit Windows completely and drop to a
true DOS prompt with no Windows running at all.<BR><BR>Hope this
helps,<BR><BR>Jayson<BR><BR>On 7/19/2018 5:45 AM, Aksel Leo Christoffersen

<P class=MsoNormal>Hi,</P>
<P class=MsoNormal> </P>
<P class=MsoNormal><SPAN lang=EN-US>I’m thinking of buying a Dectalk Express
unit, but I want a unit running the Dectalk version 4.2 firmware.</SPAN></P>
<P class=MsoNormal><SPAN lang=EN-US>So, I’m connected to the Dectalk Archive
BTSync folder, and in the hardware folder, I found a file called dtxv42.exe,
which I guess mean Dectalk Express version 4.2 CD. However, when I try to
open the file, I get a compatibility error.</SPAN></P>
<P class=MsoNormal><SPAN lang=EN-US>So if I accidently buy a Dectalk Express
unit with a version higher than 4.2, can I then use the dtxv42cd.exe to
downgrade it, and how can I use the file, when Windows can’t open
it?</SPAN></P>
<P class=MsoNormal><SPAN lang=EN-US></SPAN> </P>
<P class=MsoNormal><SPAN lang=EN-US>Thanks in advance.</SPAN></P>
