Overwrite Dialog Box

InstallShield 2020

This dialog box lets you specify whether the files of the active component (the component selected in the Setup Design or Components view) overwrite already-existing versions on the target system always, never, or conditionally based on date/time stamp or version number.

Dialog Options

list box

Select whether files on the target system are always overwritten, never overwritten, or conditionally overwritten based on date/time stamp or version number.

The following controls are enabled only if "Overwrite files BY VERSION" or "Overwrite files BY VERSION THEN DATE (if necessary)" is selected in the list box.

Note:If a file on the target system has a version number and the file on your distribution media does not, or vice versa, the file with no version number is treated as if it had a lower version number.

Version: Newer

A file on the target system is overwritten if the file on your distribution media has a higher version number.

If the file on your distribution media and the file on the target system have the same version number, or if neither file has a version number, and you selected Overwrite files BY VERSION THEN DATE (if necessary) from the list box, then whether the file on the target system is overwritten is determined by which Date/Time option you select.

If neither file has a version number and you selected Overwrite files BY VERSION from the list box, then the file on the target system is not overwritten.

Version: Newer or Same

A file on the target system is overwritten if the file on your distribution media has a higher or the same version number.

If neither file has a version number and you selected Overwrite files BY VERSION THEN DATE (if necessary) from the list box, then whether the file on the target system is overwritten is determined by which Data/Time option you select.

If neither file has a version number and you selected Overwrite files BY VERSION from the list box, then the file on the target system is not overwritten.

Version: Older

A file on the target system is overwritten if the file on your distribution media has a lower version number.

If the file on your distribution media and the file on the target system have the same version number, or if neither file has a version number, and you selected Overwrite files BY VERSION THEN DATE (if necessary) from the list box, then whether the file on the target system is overwritten is determined by which Date/Time option you select.

If neither file has a version number and you selected Overwrite files BY VERSION from the list box, then the file on the target system is not overwritten.

The following controls are enabled only if Overwrite files BY DATE or Overwrite files BY VERSION THEN DATE (if necessary) is selected in the list box.
