Download the module here. It will save as BYUTheme.mpk
Note: If you are using Mendix Studio Pro 8.8.* or 8.9.* downloading private app store modules/widgets was turned off due to security concerns. All the BYU Private App Store content can still be downloaded from the Company Content page in the Mendix App Store and then imported into those versions of Studio Pro. Upgrading to a newer version of Mendix Studio Pro fixes the problem.
After the download finishes, import BYU Theme into your project.
Right click on your Project Explorer
Select Import Module Package
