problem install framemaker 8 trial version

[menchin_elaine at emc.com]

I'm attempting to download and install the free trial version of
Framemaker 8 from the Adobe website.  It downloads fine but during the
install process I am asked for a serial number.  I don't have one since
this is a trial version.  The Adobe support person I contacted first
suggested re-downloading the sw (didn't help, the same thing happened),
then said that I cannot run the trial of Frame 8 without first removing
Frame 7 from my system.  This isn't an option; we do our documentation
work in Frame 7 here.  I just wanted to evaluate Frame 8's conditional
text features to see if we want to upgrade.  Does this ring true - do I
really need to remove Frame 7 to evaluate Frame 8?
