|When I installed Acer Crystal Eye webcam software (Suyin's "Camera_Suyin_v2.0.4_Vistax86x64_XPx86x64") from the official Acer website driver support (under Driver tab), the PLFSetL.exe process was installed as auto-start in MSConfig (which I later disabled from auto-run). Webcam works perfectly without PLFSetL.exe auto-starting, and curious, PLFSetL.exe does not starts when webcam starts. |
