Based on the images provided on the developer's website, it appears that MiPower is a Windows XP compatible application, therefore I think this is the main issue related to error 14. I've also tried to download the application from the developer's website, but it was impossible since the download form is broken. This means I won't have the possibility to test the application on various platforms.
However, you can try to set a compatibility tweak. Right click the executable/shortcut file and go to Properties > Compatibility. Choose Windows XP from the drop-down menu and then run the software.
