Thank you very much for all your replies!
Dave upgrading to new version of InTouch would cost us $5000 (more or less, some of the machines have 10000 tags runtime license but it doesn't need that many) for each machine. We have no developer license. We have plan to upgrade which involves new PLC and new HMI package and without intouch. But that is a couple of years down the road. Right now I would like to find a solution that doesn't cost as much as upgrading the Intouch software.
I have tried Oracle VM VirtualBox running on Windows XP and I had problem getting 800x600 video resolution. I have better luck with Virtual PC but Virtual PC isn't as flexible as far as the serial ports is concerned. I think this is the most promising route.
I found that the InTouch uses 2 DDE servers to communicate with 2 sections of the machines (A PLC and a weight scale feeder). I tested these 2 DDE servers and they run find under Windows XP although they were written for Windows 3.1. With them may be I can simply write an application in Visual Basic to replace the InTouch part. It will be simpler, may be not polished like Intouch, but it would do what we need and may be more to our likings. I think this is a good option also but would take me a couple of months to do.
