This is due to changes in Gatekeeper. To disable this check temporarily:
1) Make sure System Preferences is not running
2) Open a Terminal window
3) Enter the following command, typing your admin password when prompted:
sudo spctl --master-disable
This should allow you to install SuprSetr. Once you have confirmed that SuprSetr is running, it is a good idea to enable Gatekeeper again. To do this, follow the same steps, but enter this command:
sudo spctl --master-enable
You can determine the Java version that is installed by running the command "java -version" in a terminal window. Getting a terminal window is different for each operating system. For a Mac, run the Terminal application. On Windows, click Start -> Run and type cmd in the run box. For Linux, you can use xterm, gnome terminal, or any of the other terminal emulators. If the command returns version 1.8.0 or higher, you can use one of the installers for systems with Java 8 already installed.
On a Mac, just replace the existing SuprSetr application with the new one. On Windows and Linux, you can uninstall SuprSetr using the uninstaller before installing version 3. The database structure used by version 3 is not compatible with version 1, so once you install and run version 3, you cannot go back to version 1.
It is strongly recommended that you make a backup before upgrading to version 3. You can back up from the File menu within SuprSetr, or make a copy of the SuprSetr data directory. This directory is named .suprsetr (note the dot) and is located in your home directory.
Go to SuprSetr preferences and check the "Enable auto-refresh" box. Set the time that you want SuprSetr to refresh your sets. SuprSetr will check the system time and refresh your sets when the time comes. Due to the way SuprSetr checks the system time, the refresh may not begin exactly at the time you select, but it will begin within that minute.
In order for auto-refresh to work, SuprSetr must be running. If you do not want to leave SuprSetr running all the time, you can configure your operating system to launch SuprSetr a few minutes before the selected auto-refresh time. This will allow SuprSetr to do the work of refreshing your sets. If you choose to do this, you may want to enable the option "Exit SuprSetr when auto-refresh completes".
The Mac version contains the application in a disk image. After downloading and double clicking the file, you will see a SuprSetr icon. Drag the icon to Applications, and you're done. You can replace any older versions of SuprSetr that are already there.
Once you have copied SuprSetr to Applications, you can eject the disk image and delete it.
Cancel the installation. Then right-click on the installer and select "Run as Administrator". Windows will ask you to authenticate as a user with Administrator rights. You can then continue with the installation.
A user reported this fix under Windows Vista Ultimate 64-bit: "The solution I used was to copy javaw.exe from C:\Windows\SysWOW64 to C:\Windows\System32."
Send an email to firstname.lastname@example.org, or send a message to SuprSetr on Twitter. If you are seeing an error or the program is crashing, please go to the Tools menu and select Compress Logs. This will create a zip file containing the program logs that you can attach to the email.
On a Mac, drag the SuprSetr application to the trash. On Linux and Windows, run the uninstaller. If you wish to delete all the files created by SuprSetr, read the next question.
SuprSetr places its database, authorization token(s), and log files in a directory named .suprsetr in your home directory. If you want to back up your set definitions and program state, this directory contains what you are looking for. Uninstalling SuprSetr will not delete this directory, so if you want to get rid of all of SuprSetr's files, you will need to delete this directory manually.
Warning: If you delete these data files, you will lose all of your set definitions.
SuprSetr is written in Java, and should run on any 64-bit system with Java 8 or higher installed. See the Download page for more information.
