Solutions can be installed by anyone with the System Administrator or System Customizer privileges.
The next screen that opens up will show the Name / Publisher / Package Type of the solution you are installing. This screen should show the add-on name and PowerObjects as the publisher.
Click Next, and make sure to check the “Activate all processes…” checkbox, and click Next. IMPORTANT: If you do not check this box, the add-on will not function correctly.
A green progress indicator will display while the solution imports.
Once the solution is done importing, you will see a screen like the one below. The yellow bar along the top indicates that your solution has imported successfully.
