Just went through this a couple months ago.
The older version of Versaworks will work fine with windows 7,
as long as you save the file to pdf, jpeg, etc. then import that
file into versaworks.
You will need to get he versaworks 4.0 software from Roland
if you want to the print driver to install to print to versaworks
straight from Corel, etc... You can order the 4.0 disc from roland
for under $30
