What application is giving you the message? It might not be that serious.
Anyhow, you can restore from an Acronis image (that's its main purpose). But what drive set-up do you currently have? Assuming just C:, then image restore will put all of your programs, windows updates and data back to how they were at the time the image was created.
You may wish to back-up your data before restoring the image so that you can retrieve anything that is newer than the time the image was created. Programs installs, Windows updates etc. applied after the date of the image will have to be re-applied.
