It appears you have installed your SPT incorrectly. You should NOT install SPT on your Desktop, User folder, Downloads Folder or Programs Files folder. You have yours installed in your User/Documents folder. This will cause permission issues with your operating system.
You will need to remove your current SPT install and reinstall it. For example you can make a new folder in the root of your C:/ drive, name it SPT, download and put the SPT-AKI-Installer in there and run it. This will work fine.
Follow the guide on this link and you should be good to go. SPT-AKI-INSTALLER
