I need to have my MSI check the user's machine (prior to install) for the existence of a text file and place an abort condition (or end install) dependent upon the existence of this file. Can anyone suggest the best method to accomplish this.

Actually, I did figure it out and the System Search feature was used as half of the equation; to do a search of all hard drives for a file and place the file name, were it found, in the public variable, SIGFILE. This result was then used as a LaunchCondition whereby the variable was compared to the actual file name and a Launch failure issued were the file found and the variable match the file name. I then set a display message "Installation aborted, Software found". All is well again!
