DOS application in WinXP

Its a medical scheduling application called Perfect Care. The support guys at the company that made the software. Their exact statement was "we've had major problems getting it to run in DOS under XP". When asked if per chance this was unique to XP, the answer was no, it was a problem with the entire NT line's DOS ability. Their recommended solution? Upgrade to their new Windows based product. That's more or less what is going to happen, but not for another few months (the upgrade is going to a different product, but regardless it will be upgraded, so I need a solution that will run for 4-6 months) No, but I plan to. But the location is 3 hours away from me, so it isn't something I'm going to drive to give a whirl. It will wait until I am at the location doing the rest of the upgrades. It may be a simple work around, or it may be very complex, I won't know more info until I get there next week. Agreed... but I've been "told" it won't run, and I need to make it run, so I want to arrive at the site armed with options on how to get it to run. All this I knew. It may be doing some kind of hardware access, I don't know. Won't it? VPC makes the software think it is running on its own computer. So I would think the software could write to "disk sectors" inside VPC. wishes to be used. Correct, they are currently doing it inside Win95. But like mentioned above, the software developers say it doesn't work inside the NT structure. So they may do something that is restricted (they may also just need a very tweaked PIF and don't bother telling anyone that in an effort to get them to upgrade to a newer version... I really can't say). Don't know and don't know. I have not yet stepped foot on site, and the salesman that did originally spec'd out using a Terminal Emulator to access the legacy system. When I questioned why we had to purchase a new program to access something they are currently doing in Windows (ie: why not just run whatever program they are running now to access it), that is when I was put on the hunt to find the answer. After talking to the site myself, it now appears the salesman was incorrect and it is in fact running a DOS application. BUT, I haven't been there myself yet, so maybe it will turn out to just be some terminal front end. The people on the site don't really know themselves, all they could do is tell me what they do to make it run, and from that I get the impression it is a DOS application (that and talking to the developers, they said it is a DOS app). No can do. The app needs to be run side by side with other XP/2000 based apps (the new app that is dictating this hardware/OS upgrade requires either XP or 2k). So I can't do a dual boot as it will prohibit both the legacy and the new app from running at the same time (I can do a VPC type solution since that will run in a window inside XP... but VPC's pricing will probably be an issue for something that I need 5 copies for only a few months) -chris <http://www.mythtech.net>
