QlikView 11 is designed to run on an IBM PC compatible computer running Windows™. This section describes the hardware and software requirements to run QlikView on your computer.
You need a computer with:
- A Pentium II processor or higher. (Pentium ®4 or better recommended.)
- QlikView makes full use of modern multi-core processor architecture and we thus strongly recommend using such processors graphics hardware supporting color XGA resolution, or better.
- A monitor with a resolution of at least 1024 x 768.
- A mouse or an equivalent pointing device supported by MS Windows.
- A CD-ROM drive (if installation is to be made from CD).
- A hard disk with at least 150 MB of free disk space.
- Enough primary memory
You need one of the following operating systems:
- Microsoft® Windows Server 2003™; or
- Microsoft® Windows XP™ or
- Microsoft® Windows Vista™ or
- Microsoft® Windows Server 2008™ or
- Microsoft® Windows 7™
Additional Requirements for QlikView x64
- Processor supporting the x64 architecture
- 4 GB RAM
- Windows XP Professional x64 Edition™ or
- Windows Server 2003 x64 Edition™
- Windows Server 2008 x64 Edition™
- Windows 7 x64 Edition™
- QlikView 9 does not ship in a native IA-64 (Itanium) version. The 32-bit version will run on Itanium based machines with Windows, but performance can be expected to be poor. For native 64-bit Itanium support we refer you to use QlikView version 7.xx.
- The installation requires the presence of Microsoft® MDAC 2.5 or later. This is automatically installed with e.g. Microsoft Office and all versions of Microsoft Internet Explorer 5.5 and later.
- Primary Memory: Although it is possible to run QlikView with less memory, the use of a computer with at least 1 GB for 32-bit Windows and 4 GB for 64-bit Windows is recommended. The amount of memory you need for QlikView depends on the amount of data you load, and on the data structure. Too little primary memory will drastically affect the performance of QlikView in a negative way. If you notice that your computer accesses the hard disk every time you make a selection in QlikView, you either have too many programs running, or too little primary memory.
- Virtual Memory: Make sure that your swap file (the virtual memory) is large enough. The swap file should in principle be as large as possible. However, if you have limited disk space, or a lot of primary memory, you may want a smaller swap file or no swap file. The system usually takes care of the swap file size dynamically. However, if you have too little free space on the hard disk, you may get problems with your swap file getting too small. In such a case, you can fix the size of the swap file. This is done in the Virtual memory dialog, which is accessed from the task bar: choose Settings, Control Panel, System, Performance, Virtual Memory.
- 32-bit Windows sets a limit of 2 GB logical address space for any one program running (3 GB for Windows Advanced Server). QlikView can never make use of more memory than this, regardless of the size of physical memory in the computer. This limitation does not exist when running QlikView 64-bit edition.
- Defragment the hard disk before changing the swap file settings. It usually leads to a larger contiguous free hard disk area and thus a larger possible swap file.
