Description

  The present invention relates to an installation method, an installation program, and a storage medium for installing software such as an application on a computer device.

  Conventionally, in a program for installing software such as an application in a computer device, for each of at least one software installed in the computer device, a function for acquiring resource-related information including information on other prerequisite software, and an external A function for reading resource-related information update data including information on software to be installed stored in a storage medium and other software that is a prerequisite of the software, the resource-related information update data, and the resource-related information A function for determining whether or not installation is possible by checking whether or not the software that is the prerequisite of the installation target software is installed in the computer device; A function of canceling the installation process when it is refused, a function of executing an installation process of the software to be installed when it is determined that installation is possible, and updating the resource related information based on the execution result; Has been provided for causing the computer apparatus to execute the program. (See Patent Document 1).

  For example, when newly installing software, as shown in FIG. 3, a software module stored in an external storage medium and an uninstaller are copied to a computer device by an installation program called an installer. In addition, installation processing such as registration processing for the system is performed.

  After installation, software modules and uninstallers have been copied into the computer device, and an uninstall information file that records which modules have been copied and what registration has been made to the system has been recorded. create.

  Further, depending on the software, there is a method in which when already performing an overwrite installation after a new installation, the already installed software is once uninstalled and then installed.

  FIG. 4 is a flowchart for explaining a conventional example at the time of the overwrite installation.

  When an installation program called an installer is executed, a “Welcome” screen for introducing software is displayed in step S201.

  Next, in step S202, the “use license agreement” screen is displayed, and the use license agreement is displayed.

  If the user does not agree to the contract in step S203, the installation program ends and no installation process is performed.

  If the user agrees to the contract, the installation program confirms in step S204 whether the same software has already been installed.

  If the same software is not installed, a new installation process is performed, and the installation process is performed in step S208.

  If the same software has already been installed, the version is confirmed in step S205, and if it is the same or a new version, there is no need to install it, so the installation program ends.

  If the old version of the software is already installed, the old version of the software is once uninstalled and then the new version of the software is installed in order to upgrade the version.

  Therefore, in step S206, in order to uninstall the old version of the software, the installation program executes a program for performing an uninstall process called an uninstaller.

  The installer waits for the uninstaller process to end in step S207. When the uninstall process is completed, the installer performs the original installation process in step S208.

According to the above flow, the old version was uninstalled, the new version was installed, and as a result, it was possible to make it appear that the version was upgraded from the old version.
JP 2004-252633 A

  However, in the conventional example, even when new software having a new uninstaller having a new function is installed, the uninstaller executed in step S206 in FIG. 4 is an old version of the uninstaller. There was a problem that new functions could not be used.

  For example, if the uninstaller always displays a message when the uninstaller is executed, the new version will change the content of the message or request not to display it unless it is installed once with a new installation set. Since the uninstaller is not replaced, the uninstaller executed in step S206 in FIG. 4 is an old uninstall program, and the request cannot be satisfied.

  Further, in the conventional example, the software to be uninstalled is only software to be installed. For example, when the software to be installed is software of an alias obtained by integrating a plurality of software, the old versions of the software having a plurality of aliases, The new integrated software installer could not be uninstalled.

  In order to solve the above problem, the present invention replaces the uninstaller in the installed software with a new module and executes the uninstall process using this module when the uninstall process needs to be changed.

  In addition, if the software to be installed is a combination of multiple pieces of other software, the information about multiple pieces of software prior to the integration is described in the installation information file of the integrated software installer. Execute the uninstall process for all of.

  Properly control the installation.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration example of an image forming system to which the image editing apparatus according to the first embodiment of the present invention can be applied.

  As shown in the figure, in the image forming system according to the present embodiment, an information processing apparatus 100 that generates print data (including control commands, the same applies below) and a printer 170 that forms an image based on the print data. Composed.

  The information processing apparatus 100 includes a memory 110, a CPU 130, a hard disk controller (HDC) 120, a hard disk (HD) 121, a floppy (registered trademark) disk controller (FDC) 125, a floppy (registered trademark) disk drive (FD) 126, A printer controller (PRTC) 140, a keyboard controller (KBC) 150, a keyboard (KB) 151, a CRT controller (CRTC) 160, and a CRT 161 are provided.

  The memory 110 is, for example, an application 111 that manages image editing processing in the present invention loaded from the HD 121, a printer driver 112 that is software for generating print data corresponding to the printer 170, and print data to be supplied to the printer 170. A spooler area 113 for spooling, an OS (operating system) (not shown), a work area, and the like.

  The CPU 130 operates based on the application 111, the printer driver 112, the OS, and the like in the memory 110. When the power is turned on, the CPU 130 boots with a ROM (not shown) and loads the application program from the HD 121 to the OS memory 110. To function as an image forming system. Of course, the CPU 130 can access the HD 121 via the HDC 120.

  The PRTC 140 performs processing for sequentially transmitting the print data stored in the spooler area 113 to the printer 170. The KBC 150 controls the KB 151 and takes in instruction data from the user into the apparatus. The CRTC 160 is a controller that controls the CRT 161 that is a display device. These blocks 150, 151, 160, 161 and the like constitute a user interface, but may further include other blocks such as a pointing device, for example.

  The printer 170 receives the print data from the information processing apparatus 100 and an interface 171 for notifying the information processing apparatus 100 of various statuses, mainly interprets the received printer data and generates bitmap image data. The printer controller 172 and the printer engine 173 that receives the bitmap image data output from the printer controller 172 and actually forms an image. Although not shown, an operation panel and the like are also provided.

  In the above configuration, when the printer 170 is connected to the information processing apparatus 100, it is necessary to install a printer driver for generating printer data corresponding to the printer 170 in the information processing apparatus 100 at the first stage. is there. Needless to say, this installation usually only needs to be done once unless there is a specific reason.

  FIG. 2 is a flowchart showing the uninstaller replacement processing procedure of the present invention.

  Note that the processing in this flowchart is executed based on a program stored in the HD 121 and loaded onto the memory 110 by the CPU 130 shown in FIG. S101 to S110 indicate each step.

  Hereinafter, description will be given according to this flowchart.

  When an installation program called an installer is executed, a “Welcome” screen for introducing software is displayed in step S101.

  This “Welcome” screen is not displayed if it is not necessary, for example, by performing an installation process continuously with other software.

  Next, in step S102, the “use license agreement” screen is displayed, and the use license agreement is displayed.

  This “license agreement” is not always displayed in step S102, since it is only necessary to display it once when installing a plurality of software continuously.

  If the user does not agree to the contract in step S103, the installation program ends and the installation process is not performed.

  If the user agrees with the contract, the installation program confirms in step S104 whether the same software has already been installed.

  If the same software is not installed, a new installation process is performed, and the installation process is performed in step S110.

  If the same software has already been installed, the version is confirmed in step S105, and if it is the same or a new version, there is no need to install it, so the installation program ends.

  If the already installed software is an old version in step S105, it is checked in step S106 whether the uninstaller at the installation destination is a replacement target. In step S108, the uninstaller module having the new function is executed.

  In step S106, if the uninstaller is not a replacement target, such as the version of the uninstaller already updated, the uninstaller is executed in step S108 without replacing the uninstaller-related module.

  The installer waits for the uninstaller process to end in step S109. When the uninstall process is completed, the installer performs an installation process to install software in step S110.

  If the uninstaller to be replaced cannot be used in common with the new version of the uninstaller, the uninstaller for the upgrade target software may be separately stored in the installation set of the new version.

  Also, when a plurality of pieces of software that require similar replacement are installed at the same time, a version upgrade target software uninstaller may be kept separately.

  Specifically, the copy-source uninstaller-related file at the time of executing the copy in step S107 in FIG. 2 may be stored in an area other than the installation set on the external storage medium.

  FIG. 5 is a flowchart showing a processing procedure for uninstalling a plurality of old software according to the present invention.

  Note that the processing in this flowchart is executed based on a program stored in the HD 121 and loaded onto the memory 110 by the CPU 130 shown in FIG. S301 to S309 indicate each step.

  Hereinafter, description will be given according to this flowchart.

  First, when an installation program called an installer is executed, in step S301, the installation program reads an installation information file in order to acquire file information to be copied.

  The configuration of the installation information file is as shown in FIG.

  As shown in FIG. 6, in the installation information file, file information to be copied for installing the software is described, and the software to be uninstalled is described therein.

  The uninstall target software can be described in any number by adding a code indicating that it is the uninstall target software.

  The contents are “Execution module name” to search for the location of the software to be uninstalled, “Program name” to be inserted into XXX of “Do you want to overwrite XXX?” Message, Uninstall target A “window class name” for confirming whether or not the software is running, a switch for selecting whether or not to display the “Do you want to overwrite XXX?” Message, and the like are described.

  When the reading of the installation information file is completed in step S301, it is confirmed in step S302 whether there is software to be uninstalled.

  If there is no software to be uninstalled, a normal installation process is executed in step S309.

  If there is software to be uninstalled, it is confirmed in step S303 whether it has already been installed.

  If it has already been uninstalled, for example, if it has not been installed, the process returns to step S302 to check whether there is software to be uninstalled next.

  If the uninstallation target software is installed in step S303, a confirmation message for confirming whether or not overwriting is allowed is displayed in step S304.

  As described above, this message can describe the presence or absence of display in the installation information file.

  If the message displayed in step S304 is not overwritten, the process returns to step S302 to confirm the next software to be uninstalled.

  When overwriting, it is confirmed in step S306 whether the uninstaller is a replacement target. If it is a replacement target, an uninstaller-related module having a new function is copied in step S307, and the new function is updated in step S308. Run the provided uninstaller.

  In step S306, if the uninstaller is not the replacement target, such as the version of the uninstaller already updated, the uninstaller is executed in step S308 without replacing the uninstaller related module.

  The installer waits for the uninstaller process to end in step S309. When the uninstall process is completed, the installer returns to step S302 to confirm the next software to be uninstalled.

  In step S302, when all the software to be uninstalled has been uninstalled, in step S310, file copying and registration processing with the system, which are normal installation processing, are performed.
