Abstract

An object of this invention is to obviate the need of updating a master installer even when one of a plurality of software programs to be installed is modified. An install method of installing, in a computer, a plurality of software programs each having an installation setting file describing process contents to install the software continuously, installs the plurality of software programs by continuously reading out the contents of the installation-setting files of the plurality of software programs.

Claims

1. An install apparatus for installing a plurality of programs recorded in an external recording medium, comprising:

a reading unit configured to read installation-setting files of the plurality of programs from the external recording medium in accordance with one installation executable file, wherein the external recording medium stores the one installation executable file and stores, for each program, an installation-setting file and an installation target file in correspondence with each other;

a determination unit configured to determine an order for processing the plurality of programs in accordance with a sort key of the installation-setting file which is read out;

a judgment unit configured to judge whether a program corresponding to the installation-setting file is parent or not by comparing the sort keys of the installation setting files with each other according to the determined order;

a selection unit configured to select installation target program from the programs judged as parent; and

an installation unit configured to install the installation target programs in order by reading an installation instruction of next installation target program in accordance with the installation-setting file corresponding to the selected program.

2. An apparatus according to claim 1, further comprising:

an acquisition unit configured to acquire the number of installation target files of each program and a file size of each installation target file in accordance with the installation-setting files read out by said reading unit;

a calculation unit configured to calculate a sum of the file sizes of the installation target files acquired by said acquisition unit;

a determination unit configured to determine an installation progress amount of each program on the basis of the number of files of the installation target files acquired by said acquisition unit and the sum calculated by said calculation unit; and

an update unit configured to update a state of progress of installation on the basis of the installation progress amount determined by said determination unit every time said installation unit installs the installation target file.

3. An apparatus according to claim 2, further comprising a notification unit arranged to notify a user of the state of progress of installation updated by said update unit.

4. A method of installing a plurality of programs recorded in an external recording medium, comprising:

a reading step of reading out installation-setting files of the plurality of programs from the external recording medium in accordance with one installation executable file, wherein the external recording medium stores the one installation executable file and stores, for each program, an installation-setting file and an installation target file in correspondence with each other;

a determination step of determining an order for processing the plurality of programs in accordance with a sort key of the installation-setting file which is read out;

a judgment step of judging whether a program corresponding to the installation-setting file is parent or not by comparing the sort keys of the installation setting files with each other according to the determined order;

a selection step of selecting installation target program from the programs judged as parent; and

an installation step of installing the installation target programs in order by reading an installation instruction of next installation target program in accordance with the installation-setting file corresponding to the selected program.

5. A non-transitory storage medium storing a program that causes a computer to execute a method of installing a plurality of programs recorded in an external recording medium, the program comprising:

a code of a reading step of reading out installation-setting files of the plurality of programs from the external recording medium in accordance with one installation executable file, wherein the external recording medium stores the one installation executable file and stores, for each program, an installation-setting file and an installation target file in correspondence with each other;

a code of a determination step of determining an order for processing the plurality of programs in accordance with a sort key of the installation-setting file which is read out;

a code of a judgment step of judging whether a program corresponding to the installation-setting file is parent or not by comparing the sort keys of the installation setting files with each other according to the determined order;

a code of a selection step of selecting installation target program from the programs judged as parent; and

a code of an installation step of installing the installation target programs in order by reading an installation instruction of next installation target program in accordance with the installation-setting file corresponding to the selected program.
