Over on another site I saw someone quoting a message in French. Translated, it says, "acer updater for your version is not compatible with the new windows update". That fits with my experience: it was after a major Windows Update that I got this message. I followed the prompts, and got led to an Acer download page. There was a link for each of certain specific models, and one general one for the rest. I took the latter, as my machine model (5750G) was not listed. It has not worked; I am getting spontaneous "hangs" now. I didn't get a chance to explicitly apply the update; not sure whether this actually happened. (Perhaps it 'hung' before that could complete!). The component was to patch e-Power management (or something similar).
Every time I boot my laptop this message pops up and it tells me to contact Acer regarding the issue. This started to occur when I received important updates; the update was included in with my automatic updates, therefore, I would never have been able to prevent the issue. I have no idea what to do because each time I search to resolve the issue it states there is no resolution.
