Creating an executable in 64-bit mode

1. Create a specific project configuration for 64-bit. For more details, see Project configuration. This project configuration contains all the elements of your project.
2. If necessary, select the created project configuration.
3. Expand in the quick access buttons and select "Generate the 64-bit Windows executable (.exe)".
4. Follow the different steps of the wizard for executable creation.

Installing a 64-bit application

• Installing the 64-bit application only
  This mode is used to generate the setup program for the 64-bit application only. To create the setup program, on the "Project" tab, in the "Generation" group, click "Setup procedure" (the 64-bit configuration of the application must be selected). The wizard for creating the setup procedure is automatically started (see Wizard for creating the setup program).
  Note: The 64-bit application installer is also a 64-bit program.
• Installing the application in 32-bit or 64-bit mode (with adaptation according to the deployment system)
  WINDEV allows you to create a unique setup containing both the "32-bit" application and the "64-bit" application. The version to install will be automatically selected according to the operating system of the user. Let's take a look at this option.

Combined 32-bit/64-bit installation

1. Generate the executable and the 32-bit setup procedure.
   • If necessary, display the 32-bit configuration from the "Project Explorer" pane.
   • Generate the 32-bit executable and Procedure: click on among the quick access buttons.
2. Generate the executable and the 64-bit setup procedure.
   • If necessary, display the 64-bit configuration from the "Project Explorer" pane,
   • Generate the 64-bit executable and Procedure: click on among the quick access buttons.
3. Generate the combined installation: under the "Project" pane, in the "Generation" group, click on "Setup procedure" and select "Generate a 32/64-bit combined installation".. The following window appears:
   
4. Specify the paths of the different setup programs (WDF files of 32-bit and 64-bit setups). If these files are not created or updated, you have the ability to regenerate the different setups.
   Note: It will be possible to modify the new features help displayed during installation.
5. In the next step, specify the options for generating the combined setup:
   • single generation directory.
   • directory cleared before generation.
   • directory for creating the combined setup.
   • compression format of combined setup (Zip or 7Z).
6. Validate.
7. If you have requested the generation of setup programs, finish the different wizards for generating the executable and the setup program.
8. The combined setup program is generated.

• The combined 32/64-bit setup is not available for the multisite setups.
• The version history defined for each installation program is managed: it is possible to return to a previous version of the software..
• Combined plant signing is available: each plant can be signed.
• Installation medium: each installation must have a single directory as its installation medium.
• The setup program of the 32-bit application is a 32-bit program. The setup program of the 64-bit application is a 64-bit program.
• The combined 32/64-bit setup can use different and custom setup programs. Simply select the "WDF" file that corresponds to the desired setup program.
