The Installer Error Handling dialog appears when you choose Error handling... on the Installation page. It allows you to change the way that Setup will respond to errors during the installation process. In particular, it allows you to suppress some errors, which makes the installation more likely to succeed even in the face of problems. However, it also means that your application must be prepared to deal with potentially incomplete installations.
Note - During uninstallation, most errors are ignored regardless of the following settings. This is because during uninstallation, recovery of a partially uninstalled application is all but impossible, so Tarma QuickInstall will simply continue and try to clean up as much as possible.
Check the boxes in this section to have Setup ignore those particular errors; clear them to cause those errors to abort the installation process.
Check this box to ignore file installation errors; clear it to abort the installation if one or more files cannot be installed. You should rarely, if ever, check this box, because the resulting application may be incomplete and unable to start.
Check this box to ignore errors during file registration; clear it to abort the installation if one or more files cannot be registered. (File registration is subject to the options that you select on the Installation file settings pane.)
Check this box to ignore shortcut installation errors; clear it to abort the installation if one or more shortcuts cannot be installed. (Shortcuts are only installed if their target file is present on the system; it is not considered an error if a shortcut is not installed because the target file is missing.)
Check this box to ignore errors during registry editing; clear it to abort the installation if one or more registry editing actions fail.
Check this box to ignore errors during INI file modifications; clear it to abort the installation process if one or more INI file modifications fail.
Check this box to ignore errors during environment variable editing; clear it to abort the installation process if one or more environment variable modifications fail.
Check this box to ignore errors in custom actions; clear it to abort the installation process if a custom action fails to execute.
