This property only applies if a file(s) that is being installed already exists on the target system. If so, then this property controls how the install engine compares the file being installed to the current file. Select one of the following:
- Replace by Date - Compares the two files by only checking each file's "last modified" date.
- Replace by Version - Compares the two files using version information, if possible. If it cannot obtain version information for either of the files, then both files are assumed to be the same.
- Replace by Version then Date - Compares the two files using version information, if possible. If it cannot obtain version information for either of the files, then it compares the files by their last modified date information.
