System Requirements

Computer and processor 1 gigahertz (GHz) processor or higher. For large projects a 64-bit processor is recommended.
Memory 512 megabytes (MB) of RAM or higher. For large projects a minimum of 2GB is recommended.
Hard disk 40MB available disk space.
Display 1024 x 768 or higher-resolution monitor. At 1024 x 768, a maximum of 96 DPI (or 100% font scaling) is supported.
Operating system Windows XP or later. For large projects 64-bit editions of Windows are recommended.
Internet An Internet connection is required for the use of the online training system and for transferable licenses. If you have extra firewall or network security as part of your systems then it must allow Q to use HTTP.
Additional software Microsoft .NET Framework 2.0. This is included with Windows Vista and later, and is also automatically installed with Windows XP Service Pack 3 (SP3). You may download it from Microsoft. If you're unsure whether .NET is installed on your computer, try installing Q first; the installation wizard will stop if it cannot be found.

To export tables or charts to Microsoft Office, you must have Microsoft Office 2000 or later installed. Office 2007 or later is recommended.
Other Q can only run on Apple Macs within Parallels or other Windows emulation software.

To use Q Professional on a Terminal Server, you must purchase a Transferable license.

For System Integrators

This information is provided for the benefit of IT people who need to assess Q or make it part of their standard builds.

  • We are not aware of any conflicts between Q and other applications.
  • Q installs everything into its own directory in Program Files, except for RtoQ.dll, which it installs into Windows\System32. This DLL is used by the R program if integration between the two is required.
  • Q installs registry entries for its own file extensions, but does not modify registry entries created by other programs.
  • Q does not replace any shared DLLs.
  • Q's setup program can be run in silent mode for automatic installation.
  • Q "drives" (via COM) Microsoft Office when exporting tables and charts. Q will only talk to Office when you export, so it cannot discombobulate office in other situations. Q has been tested with Microsoft Office 2000, 2002, 2003, 2007 and 2010.
  • Program Files\Q\License.lic requires special permissions: it must be writeable by "Everyone". This ensures the license is shared between users on the same physical computer (doesn't use Roaming settings).
  • So that these special permissions don't get lost, the Program Files\Q\License.lic file must always exist (even if it has a size of 0) and shouldn't be deleted.
  • For automatic deployment, the installation program (QSetup.exe) can be run with the "/silent" parameter. For this to work properly you must ensure that it runs as an administrator and that no old versions of Q are still running.
