When UAC is on, if you run PowerBuilder under a non-administrator login account the first time after you install Appeon Developer or register the Appeon Developer toolbar (by using the ADT Register tool), the Appeon Developer toolbar does not respond when you click it in PowerBuilder. And when you exit PowerBuilder, you will be prompted with the following dialog box, and then when you open PowerBuilder again, the Appeon Developer toolbar works normally.
Solution A: Run PowerBuilder in the "Run as administrator" mode. After the first time, you can run PowerBuilder in the normal mode.
Solution B: Choose Windows Start > All Programs > Appeon for PowerBuilder 2016 > Appeon Developer > Appeon Toolset.
Solution C: Exit PowerBuilder and run it again. The Appeon Developer toolbar works normally except for the first time. Note that this solution does not work on Windows 8.
