Computer / System Requirements

  • OCAD 11 requires Windows Vista (Service Pack 1), Windows 7, Windows 8 or Windows 10 (32 or 64 bit). OCAD 11 is a 32 bit software.
  • We strongly recommend for Windows Vista und Windows 7 to use the default Aero Theme to avoid unnecessary screen redraws or erased maps when moving dialogs.
  • 50 MB of free disk space for the installation
  • At least 1 GB RAM (depends on the size of open maps and background maps). The OCAD program without any open map needs only 70 MB RAM.
  • OCAD 11 is a 32 bit software and can allocate up to approx. 3.5 GB RAM (32-bit Windows XP, Vista™ and 7 consult the page Physical Memory)
  • Screen resolution: 1280 x 1024 or higher recommended
  • OCAD 11 Professional Edition: We recommend to install the Borland Database Engine (Shape import, dBase files) and the Microsoft Access Database Engine 32-bit (Access and Excel files).

Hint.jpg It is not possible to install the Access Database Engine 2010 32-bit edition if the Microsoft Office 2010 64-bit edition is installed on the same computer. The solution is to install the Access Database Engine 2007 32-bit edition.

Hint.jpg Please note that the current Service Update 11.6.0 is not compatible with Windows XP because the OCAD 11 program file is signed with SHA-256.
