You can enable or disable this mode. If the state is enabled, the installation will not be interrupted in case of an error when unpacking or copying files. In this case, you should check the value of the catch_result variable after unpacking or copying the files. If its value is 1, then there was an error and you will have to assign to zero its value after processing the exception. The variable catch_error contains the error type as a string errfile - write error, errdir - directory creation error, errdisk - error the opening of another volume, in case of a multivolume installation. The variable catch_name is the name of the file or directory where the error occurred.
