System requirements for Opera for Windows

NOTE! These system requirements are for the Windows version of Opera. There are separate requirements for Linux and Mac

Minimum configuration for Opera 9:

  • 20 MB of free disk space
  • Any system running Windows 95 (or later)

These requirements only apply to Opera. Third-party plug-ins such as Flash, Java and others may have additional requirements.

Recommended configuration for Opera 9:

  • Pentium II class system with 64 MB of RAM and at least 50 MB of free disk space
  • Windows 98 or higher

While Opera 9 should run on any 32-bit version of Windows, the performance on computers below Pentium II class may be less usable. Legacy versions of Opera, such as Opera 6 and below, are better suited for such systems.

Legacy versions of Opera for Windows are available from the Opera archive at arc.opera.com.

Installing Opera 9 on Windows 95, 98 or NT 4.0 requires the Windows Installer to be installed on your system. Alternatively you can select the classic installer when downloading Opera, but then you must manually download the language files for languages other than US English.
