From the VMware Workstation manual:
Use virtual machines or system images created with products from other companies such as Norton, Symantec, and StorageCraft.
Someone isn’t very good at checking their facts. I do have to wonder how someone manages to find out that Symantec has a system imaging product without knowing that Norton is a Symantec brand name. You’d think the logo on the box or web site would be a clue.
