Overview
Modern computers (servers and desktop computers) are equipped with 64-bit operating systems.
The main difference between a 32-bit and a 64-bit system is that in 64-bit, applications and the system are no longer limited in terms of memory allocation.
In "32-bit" configurations the operating system is limited to 4 GB, while in "64-bit", there is nearly no limit (18 billion GB).
WINDEV and WEBDEV include the following features to help you develop 64-bit sites and applications:
  • A framework available in 32 and in 64-bit
  • WEBDEV Application Server, available in 32 and in 64-bit
  • HFSQL Client/Server server, available in 32 and 64-bit versions. For more details, see HFSQL Client/Server.

WINDEVWindows

To create a 64-bit application

  1. Develop your 64-bit application. A 32-bit application can be changed into a 64-bit application.
  2. Deploy your application.
WEBDEV - Server code

To install a WEBDEV website on a 64-bit server

  1. Install a 64-bit WEBDEV Application Server on a 64-bit Web server.
  2. Develop and deploy your WEBDEV website on the Web server.
Note: A site compiled in 64-bit mode can be used with a 32-bit or 64-bit server. A 64-bit server can only display 64-bit sites. If the site was not compiled with the "64-bit" option, an error will be displayed when the site is started.
