To install the windows app, please follow the following steps:
- Go to Settings

Now, go to the folder where you saved the two files downloaded (JSDCOGApp.Windows10_220.127.116.11_x86_x64_arm.cer & JSDCOGApp.Windows10_18.104.22.168_x86_x64_arm.appxbundle). Click to and install.
NB: For the first launch, the application may not display lessons immediately since it will be syncing the lessons from the online server. Therefore, you need to get to the lessons tab and let it stay for some few seconds and then select the year.
