I. If you are using ChemBioDraw Ultra 15.0 on a PC:
You need to reactivate with your existing serial number. Reactivating will extend your current software's license until Sunday, November 09, 2015.
1. To reactivate, launch the ChemDraw application and click 'Activate' on the 'Help' menu then put in your serial number (it shows up automatically if you originally activated on the same machine).
2. Click on 'Activate over the Internet' to complete the activation. If that fails (because you don't have an Internet connection) then you can activate by phone, fax, or email to receive an activation code.
3. The software will display a warning message one month before the previous expiration date, and you can close that window then click 'Activate' on the 'Help' menu.
4. If your software has already expired, you will be immediately prompted to activate when you launch ChemDraw.

Can faculty and students install the software at home?

Absolutely. A professor can install the software on a home computer. The software can be installed on home computers and school computers, or on many school computers. The same holds true for students. As long as they are covered by the site license at all, which means that they have a valid email address at your school, they can install the software on as many computers as they want.

I have a Mac, is this available to me?

Yes, the software is available for both Windows and Macintosh users. You will be sent serial numbers for both types of computers and you may choose which one to download from the Cambridge Software URL. Are Manuals available? Manuals are available to download in the form of PDF. They are available for download from the same site.

What happens after a year?

We expect that most schools will renew their license rather than let it expire. If your license expires, you will only lose the ability to create new data and to edit existing data. You will still be able to view any data you had created while under the site license.

What if the software is updated before our license expires?

The Annual Site License allows you to use the latest version of the software, regardless of when that version was released. Each user will have to download and install the update, of course, but they are certainly allowed to do so under the terms of the license.
