You can have RH HTML from 6 & 7 installed, it's dual
installs of RH for Word that will give grief.
What do you mean by "I went to open my project and it was no
longer in RoboHelp7."
I am also not sure how a file can "disappear".
From the rest of what you describe, it sounds as if the XPJ
file association is with RH6 which is what I would expect, later
versions don't take over from earlier versions. If you open RH7 and
browse to the RH7 project, it should open OK.
When you have resolved this, find your Send To folder and add
shortcuts to RH6 and RH7. Then you can right click any XPJ and
choose the appropriate version.
