Hello,
After multiple hours spent googling for a solution I decided to give it a try over here. Hope you can help me.
My Aspire 5750g is overheating which is an already known issue and I have done everything to keep the processes low.
- Am using a fresh windows install.
- Am using the newest GPU driver.
- Am using the newest BIOS (1.21 for my 5750G).
- Have cleaned dust out of heatsink and fan.
I also know from edge to edge this topic:

I have had used Acers FanController_V1.0.0.3 without any problems untill today... Somehow after some changes with deleting/installing a few programs I wanted to start FanController_V1.0.0.3 and crashed.
So I didn't hesitate and reinstalled it asap.
When I was trying to reinstall this is what pops up: 
So please if someone could help me because without the fan controller my notebook is useless...!
Regards,
Chris
