BEST Plus Administrator Practice CD. I don't know what you mean by .exe.
I've given you the exact full name. You know what, I've had it with Mac. I bought it because years ago I taught journalism and used a mac to lay out our paper. Easiest computer I ever used. Now, forget it! I have to drive to Charlotte to get help. Think I'll pull out that Toshiba I put away when I paid big bucks for this computer. I think Apple should use a warning label to potential buyers. Sorry. I know this isn't your fault, but I've never, ever had so much trouble being able to use a laptop.
I am another expert on the site and I think I understand the issue you are having
The instructions on the BEST Plus webpage clearly states that "Mac users will need to have Boot Camp, Parallels, or VMware Fusion installed". So you will need to install one of these application on your Mac so it can it read and run that program from the CD or, like you said, use your old Toshiba laptop
Hope this helps
