This help page presents the configuration required to install WINDEV, WEBDEV or WINDEV Mobile in 64-bit mode.
Why installing a 64-bit version?
Installing WINDEV, WEBDEV or WINDEV Mobile 64 bit is recommended (except if your projects use an unavailable feature, see list below). This setup is recommended if you are using projects that include several elements (more than 1500).
The limitations for installing a 64-bit version are as follows:
  • Native Connectors (Native Access) Progress and Sybase are not available in 64-bit.
  • The connections from the data model editor are performed in 64 bit. If a connection is performed toward an external database, the client or ODBC driver or OLE DB provider of this database must also be installed in 64 bit.
  • The former Hyper File 5.5 analyses cannot be imported.
  • The former RAD compatible with version 11 is not available.
  • The Webservices in "Compatible version 14" mode cannot be imported.
  • WINDEV Mobile/CE:
    • Windows Mobile/CE: The Go (terminal) of Windows Mobile/CE projects is not available.
    • Windows Mobile/CE: automatic modification of the data of a Windows Mobile/CE terminal from the PC is not available..
    • Windows Mobile/CE: Installation generation for Windows Mobile/CE is not available.
Required configuration
The following configuration is required for the development computer:
  • 4 GB or RAM (8 GB or more recommended).
  • 2 GB of disk space (4 GB for a full setup: hundreds of examples are supplied with the product).
  • running 64-bit Windows.
The format of projects and project elements is independent of the compilation mode of the editors. All the source elements (projects, windows, reports, classes...) can be opened by a 32-bit editor then by a 64-bit editor (and conversely).
A 32-bit version and a 64-bit version of the same software should not be installed on the same development computer.
However, if the same development configuration is hosting a 32-bit version and a 64-bit version of WINDEV, WEBDEV or WINDEV Mobile:
  • the two versions must be installed in different folders as proposed by default.
  • the two versions must not be run simultaneously.
Minimum version required
  • Version 19
