    I am a scientist purchasing a new tablet PC that runs Vista. We have a piece
    of scientific hardware, a Biorad Icycler that has software that will work
    only with XP and installs drivers for the serial and parallel ports (I
    believe that this is where the incompatibility with Vista lies). I do not
    want to actually run the instrument with the tablet, but I want to install a
    copy of the software for standalone data analysis. When installing the
    program you have the option to select a standalone configuration, but the
    drivers are still installed. They are just never used in this mode. I need
    this so that data can be copied into Excel. I would also like to copy
    portions of the program screen into OneNote. Will virtual PC support this
    functionality without effecting the operation of Vista? Thank you for your

    From your description it sure sounds like it would, though there may
    be a problem with input into the VM -- if you have a real keyboard on
    the tablet or attach a USB one, it should be good, but the VM doesn't
    work real well with just the pen...

    VPC2004/2007 passes through up to two serial porst to the guest
    system. Depending on the way the serial port is handled in the guest
    you might not get it working with VPC2007, however. There is a bug
    that never got corrected in the serial port emulation for VPC2007. :-(
    But if you use VPC2004 instead this will work. But then of course it
    is *not* possible to have Vista as the *host* system (Vista was the
    reason MS upgraded VPC to VPC2007).

    Furthermore, in order to use the parallel port pass-through you MUST
    have a real parallel port on the host! It is *not* possible to use the
    USB connected printer port adapters because these are just fancy
    printer drivers. Most certainly your package uses the printer port as
    a way to have digital I/O to the data collection equipment (like my
    company does) and in that situation USB printer ports are totally

    There may be another use for the printer port and this is in order to
    handle software protection devices (dongles). This also does not work
    unless you have a *real* printer port on the host.

    Been there done that....
