just keep in mind that changing that LogFile variable to that only assists when the log file is set to that location.
Rift Devs do not require the log to be placed anywhere any longer, and they allow users to change there log location to anything that want via the cfg file.
I accounted for this in my script on the forum using multiple lines of code, but specificly focusing around the following to correctly put this LogFile location. When this is set within the config as a period (.) or if it's not present, then it defaults to the AppData location as you stated in your reply.
IniRead, LogFile, %A_AppData%\Rift\rift.cfg, Client, DocumentsDirectory
without that, if users changed there logfile location to save for example "C:\Logs" .. then your script still wouldn't work, unless they manually changed it in the script.
Just fyi is all.
