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 comprising:

extracting a feature point after having analyzed data file,

deciding a version of an application suited for the data file based on an extracted feature point,

judging whether an application program of a decided version is already installed, and

newly installing an application program of the version when the application program is not installed.

2. An installation method of an application mentioned in

claim 1

, wherein:

the feature point is a reserved word of a macro instruction included in the data file, and

the version is decided by detecting the reserved word peculiar to each version.

3. An installation method of an application mentioned in

claim 1

, wherein:

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

the version is decided by detecting the syntax pattern peculiar to each version.

8. An activation method of an application mentioned in

claim 3

, further comprising:

eliminating an existing file in case that a vacancy domain is insufficient when the application program is executed.

4. An activation method of an application comprising:

extracting each feature point after having analyzed equal to or more than two data files,

deciding a version of the application program that the data file is readable based on the feature point,

simultaneously displaying the data file and an application program of a version decided thereby, and

actuating the displayed application program in relation to any one of the data files.

5. An activation method of an application mentioned in

claim 4

wherein:

the data file is displayed with a different symbol figure by each version corresponding to the application program.

6. An activation method of an application mentioned in

claim 4

, wherein:

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

7. An activation method of an application mentioned in claim 4, wherein:

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

9. A record medium that a program is recorded, comprising:

a step for extracting each feature point after having analyzed equal to or more than two data files,

a step for deciding a version of the application program which can read the data file based on the feature point,

a step for simultaneously displaying the data file and an application program of a version decided thereby, and

a step for actuating the displayed application program in relation to any one of the data files.

10. An apparatus for executing an application program comprising:

a means for extracting each feature point after having analyzed equal to or more than two data files,

a means for deciding a version of the application program which can read the data file based on the feature point,

a means for simultaneously displaying the data file and an application program of a version decided thereby, and

a means for actuating the displayed application program in relation to any one of the data files.

11. An apparatus for installing an application comprising:

a means for extracting a feature point after having analyzed a data file,

a means for deciding a version of an application suited for the data file based on an extracted feature point,

a means for judging whether an application program of a decided version is already installed, and

a means for newly installing an application program of the version when the application program is not installed.

12. The storage medium that memorized a program for sequentially executing:

a step for extracting a feature point after having analyzed data file,

a step for deciding a version of an application suited for the data file based on an extracted feature point,

a step for judging whether an application program of a decided version is already installed, and

a step for newly installing an application program of the version when the application program is not installed.
