This file was part of bundled software that came with an Epson printer. The ArcSoft software was OK, but when I found other software I preferred, the ArcSoft product did not uninstall well. It is relatively small, but still increases the computer's commit charge for no reason if you do not use the ArcSoft software.

The program can't start because MagCore.dll is missing from my computer. I don't know how to reinstalling the program to fix this problem

ArcCon system resource is also part of software that comes with Epson scanners, like my PERFECTION V500 PHOTO scanner, and is directly tied with ACStart program controlling the scanner.

Best practices for resolving ArcCon issues

A clean and tidy computer is the key requirement for avoiding problems with ArcCon. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
