If you performed a backup of your system, when the mentioned application was working fine, you can perform a restore of your system to that moment. If you used the Windows inbuilt backup function, you need to go under Start > Control Panel > Backup and Restore > select the backup and click Restore. In case you used a third party tool to perform the backup, you will need to use the same tool to restore to the point where the application was working.
If you didn't perform any backup action on your PC, and the mentioned program crashed, to restore it, first you need to Uninstall it from your PC. To do this, go to Start > Control Panel > Programs and features > select it and press Uninstall. After you did this, go to the following download website, properly select your computer model and download the latest version of Empowering Technology from there, in order to install it.
