ePower in clean Win7 64 install

Is there any possibility to interact with ePower in Windows 7 clean installation? In original Vista that came wit notebook it had tray icon, but when I install this app in Win7 from provided archive (ePower_Acer_4.07.3008_Win7x86x64), there is no tray nor any launcheable app, even through there is epowertray.exe running in memory. An when I press ePower button (green battery with leaf), nothing actually happens, only indication is that icon is green lit and if I install launchmanager, there is visual indication on display too...

 

Same case here for me.

Tried everything, i could not solve it.
On its way to service.

 

It is suppose to preload a fix number of energy saving modes into the laptop and switch to it whenever it detects it is on battery automatically with no human interaction.
Not meant to be modifiable but you can see the settings in Windows Registry.

 

But win7 has powerfull powesaving schemes, do I really need to install another app doing the same job? It eats a bit of cpu time to time, so it actually does something. But does it have actual benefit?

 

It gives the convenience of setting hardware settings to optimized pre-setted low power mode when AC is disconnected.
Most of the time it does nothing.
For some Acer System it is essential to the operation of the ECO button on the laptop.
