Notice: You need to put WoW CacheDeleter & Starter (Universal).exe to your WoW folder where WoW.exe or WoW-64.exe is.
Optional 'wowcdns.cfg' file usage
You can create file named 'wowcdns.cfg' inside WoW folder where WoW executable is, you can determine which WoW executable will be launched.
For example, if CustomWoWExecutable.exe is written in wowcdns.cfg file, WoW CacheDeleter & Starter (Universal).exe will start that defined CustomWoWExecutable.exe instead of launching WoW.exe or WoW-64.exe after Cache files removal.
Optional 'WoW.@RunOverride.exe' usage
Similarly to 'wowcdns.cfg', you can rename your prefered executable to 'WoW.@RunOverride.exe' which will be started instead of WoW.exe or WoW-64.exe (Notice: if 'wowcdns.cfg' exists, file written in it has higher launch priority that 'WoW.@RunOverride.exe' so it will be ignored).
If you want to determine which executable to start, rather use 'wowcdns.cfg'.
