This checkbox will tell the patcher to parse all the pre-executables (if any) BEFORE the Splash Screen is shown.
This option tells the patcher to parse the pre-executable list before the splash is shown. If this is left unchecked, the patcher will show the Splash Screen first THEN parse the pre-executable list before going into the patching process.
There are no obvious pros or cons to this option switch, however it is there incase you come across a particular situation in which it’s a necessity to run the pre-executables before the Splash.
For normal circumstances, we recommend leaving this option off so the Splash is shown before the parsing of the pre-executable list.
