Solution

Your "process-excludes.cfg" (C:\Program Files\Aurora-Agent\config\process-excludes.cfg) configurations probably has a missing escaping "\" in the process-path (aurora searches for those process paths using regular expression):

Wrong:

^"C:\Program Files (x86)\

Correct:

^"C:\\Program Files (x86)\\
