I think you guys are making this more difficult then it is lol. Or maybe I just like my way better. Here's my two cents. Set WPI to use UNC (i.e. \\pcname\nero\install.exe or w/e). Use batch file to copy all files under wpi directory to local disk. use AutoIt to start the batch file and start wpi when done copying. after wpi has finished have it run another batch to delete wpi folder (if so desired) and then delete itself.
