ChemOffice/ChemDraw Professional Support

ChemDraw Reactivation

Penn Chemistry has renewed our license for ChemDraw products for another year.  This extends the license until November 2017.  If you obtained a license prior to Sepetmber 2016, you will need to reactivate your license. Follow the instructions here to reactivate your license.

About the License

The Chemistry Computing Facility has an annual Site License for PerkinElmer's ChemOffice Professional 15 for Windows and ChemDraw Professional 15 for Mac. If you have not taken advantage of this resource yet, please follow the instructions below to request a license.

The license is for both the Windows and Mac versions of the Software. Please note that the Mac version does not contain some features that the Windows version has (most notably, Chem3D). Details about this software can be found here.

Only valid Faculty, Staff, and Students of the Chemistry Department at Penn are eligible for the license. Eligibility will be based on inclusion in the Chemistry Department Directory and the UPenn online Directory. Please be sure you are included in one of these directories to gain access to the software quickly.
