Ascent Capture – ACSVC.EXE
Acsvc.exe is the Ascent Capture Service. It installs with Ascent Capture by Kofax, a DICOM Group Company. Ascent Capture automates the capture of information from documents and forms, and delivers reliable, retrievable information into your business applications. More information can be found at http://www.kofax.com/products/ascent/capture/index.asp.
This file doesn't necessarily need to be running all the time but it will need to be running when you capture screens. So if this is a utility that you use frequently, you may find it most convenient to let it run on system startup.
