           Summary: Dragon NaturallySpeaking 7 install fails with negative
                    amount of memory reported
           Product: Wine
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org

I'm running Ubuntu 8.04 on a dual boot machine with 3GB memory which can
comfortably run Dragon NaturallySpeaking Preferred 7 under XP. I'm having
problems installing Dragon NaturallySpeaking 7 in Wine and believe there may be
a bug.

Regardless of whether I run "wine /media/cdrom1/autorun.exe" or wine
/media/cdrom1/setup.exe or if I copy the cd contents to the hd and run the
install from the hard disk, the install looks promising for only a few moments. 

Then an error message which describes the minimum requirements for DNS 7,
finishing with:  "Your computer does not meet the minimum specifications for
installation of Dragon NaturallySpeaking" and it reports -1052Mb memory -ie
***minus*** 1.052 GB memory.  Then the install allows me to withdraw
gracefully, no crashes or other problems, which is a tribute to the stability
of Wine itself.

This behaviour happens under Wine 1.00 from the Ubuntu repository and also
under Wine 1.1.6.

My guess is that fault lies with the the Dragon installer, which is not able to
recognise 3GB and is therefore unable to install, having misreported the total
physical memory as a negative quantity as a result of a register overflow.

I remember causing similar odd results myself when programming in C in what now
feels like another lifetime!  Usually the silly result would be the consequence
of a register overflow thanks to my very poor programming skills.

I'm not all that familiar with the intricacies of Wine: could it be that there
is a command line option available which limits the amount of physical memory a
program running under Wine can see? Or is this a bug?

Teight
