Abstract

Without letting a user execute a cumbersome judgment of a version, an application program of the most suitable version is installed for data file automatically, thus an automatic activation of the application becomes possible. Firstly, a document file of a readout target is analyzed, a feature point as reserved word of macro instruction is extracted, and a version of an application suited for the document file is distinguished by an extracted feature point. Secondly, it is judged whether an application program of the version distinguished mentioned above is installed already. When found not being installed based on this judgment result, an application program of the version is newly installed.

Claims

1. An installation method of an application program, comprising:

extracting a reserved word of a macro instruction in a data file automatically after having analyzed the data file based on a stored reserved word, the reserved word extracted being a content within the data file;

selecting a version from an installed version list for the extracted reserved word automatically, wherein the reserved word is an application program that is to be installed;

determining whether the selected version of the application program is already installed;

installing the selected version of the application program automatically upon determining that the version of the application program is not installed; and

executing the selected version of the application program automatically by executing the macro instruction.

2. The installation method mentioned in claim 1, wherein:

the selecting of the version of the application program suited for the data file is decided by the extracted reserved word and the installed version list of the application program.

3. The installation method mentioned in claim 1, wherein:

a syntax pattern of the macro instruction included in the data file is extracted, and

the version of the application program suited for the data file is decided by the syntax pattern and the version of the application program enabled to read the syntax pattern is determined by comparing the syntax pattern with stored syntax patterns.

4. The installation method mentioned in claim 3, further comprising:

eliminating an existing file if insufficient space exists when the application program is executed.

5. A method of activating an application program, comprising:

extracting at least one of a plurality of reserved words of macro instructions in a data file automatically after having analyzed the data file based on stored reserved words, the reserved words extracted being contents within the data file;

selecting a version from an installed version list for the extracted reserved words automatically, the reserved words being an application program to be installed;

displaying simultaneously the data file and the selected version of the application program; and

activating the selected version of the application program automatically by executing the macro instructions.

6. The activation method mentioned in claim 5, wherein:

the data file is displayed with a format corresponding to the application program.

7. The activation method mentioned in claim 5, wherein:

only the data file corresponding to a version of the application program is displayed when the application program is selected.

8. The activation method mentioned in claim 5, wherein:

the installation of a corresponding application program is executed when an application program corresponding to the data file does not exist.

9. A computer storage medium on which an application program is recorded, the application program when executed by the computer, causes the computer to execute the functions comprising:

extracting at least one of a plurality of reserved words of macro instructions in a data file automatically after having analyzed the data file based on stored reserved words, the reserved words extracted being contents within the data file;

selecting a version from an installed version list for the extracted reserved words automatically, the reserved words being an application program to be installed;

displaying simultaneously the data file and the selected version of the application program; and

activating and installing the selected version of the application program automatically by executing the macro instructions.

10. An apparatus for activating an application program, comprising:

a memory storing reserved words;

an extracting unit extracting at least one of a plurality of reserved words of macro instructions in a data file automatically after having analyzed the data file based on the stored reserved words, the reserved words extracted being contents within the data file;

a selecting unit selecting a version from an installed version list for the extracted reserved words automatically, the reserved words being an application program that is to be installed;

a displaying unit simultaneously displaying the data file and the selected version of the application program; and

an activating unit activating the selected version of the application program automatically by executing the macro instructions.

11. An apparatus for installing an application program, comprising:

a memory storing reserved words;

an extracting unit extracting at least one of a plurality of reserved words of macro instructions in a data file automatically after having analyzed the data file based on the stored reserved words, the reserved words being a content within the data file;

a selecting unit selecting a version from an installed version list for the extracted reserved words automatically, the reserved words being an application program that is to be installed;

a judging unit judging whether the application program of the selected version is already installed; and

an installation unit installing the selected version of the application program automatically when the selected version of the application program is not installed; and

executing the selected version of the application program automatically by executing the macro instructions.
