Hello KollinD, Buying a full course gives you access to that course for that version indefinitely. If you purchase the Mastercam 2018 Mill Essentials eCourse, for example, you can come back in at any time in the future to refresh yourself with the videos or the eBook. However, you don't automatically get access to newer versions of the course (e.g., 2019 or 2020) or other courses (e.g., Mill Advanced). The Sitewide Subscription gives you access to all eBooks and all eCourses for as long as you keep up your subscription. You get all currently released materials as well as access to new materials as they are released. If you buy a year-long subscription today you'll automatically get access to all of the materials for the next version of Mastercam when it's released next year. A week before your subscription is set to expire you'll be sent a reminder asking you to renew. If you choose not to renew your access will automatically expire and you will no longer be able to access the eBooks and your progress in the courses will be erased. You will not be automatically charged for renewal so there's no risk of forgetting to cancel when you're finished and being on the hook for an additional year. You also don't need to buy anything from eMastercam.com to access the free Home Learning Edition of Mastercam 2019.

Depending on the complexity of your parts it may be fine. If all you're doing is simple 2D work then it might not be a problem but if you're doing anything more complicated the money saved by using integrated graphics and a cheap processor will be lost very quickly in terms of time waiting for the computer to work through things. Hopefully you can convince them to spend a bit of money now to make a bunch more with improved efficiency down the line.

Disabling hardware acceleration will lower performance when working with more complex parts. Simple training parts shouldn't see any significant problems but most parts used in industrial settings will see a performance hit. Of course, integrated graphics cards aren't recommended for Mastercam. If you're using this computer for work it'd be best if you acquired a decent graphics card.

Hello Giang, When you say the backplot was acting up all weird, what exactly was it doing?

The solution to this is actually counterintuitive. Go to your Windows settings and change your default printer to Microsoft XPS Document Writer.

I had that exact error message when installing a different program. Try disabling your antivirus temporarily, then right-click on the install file and select "run as administrator."
