You can install Internet Explorer 11 in your localized environment by using either the English version of the installer or a supported language version of the installer for your localized environment.
If you don't use the English version of the Internet Explorer 11 installer, make sure that the language version of the installer matches the active language of your operating system. If the language versions don't match, Internet Explorer 11 stops the installation. Additionally, you receive the following error message:
Wrong version of Internet Explorer installer.
For example, you experience a language mismatch if you try to install a Spanish version of Internet Explorer 11 on a computer that is running the Catalan-localized version of Windows. Although Spanish is the base language for the Catalan Language Interface Pack (LIP) language, you must use the specific Catalan version of the Internet Explorer 11 installer in this environment.
To install Internet Explorer 11 in your active language, download the correct Internet Explorer 11 installer for your operating system version. To do this, go to Download Internet Explorer 11
, and then locate the download file for 32-bit systems or 64-bit systems, as appropriate.Note
This information applies only to non-English versions of the Internet Explorer 11 installer. If you use the English version of the installer in a supported non-English environment, the installation process continues in English, but the installed program will match your operating system language.

We do not recommend this workaround, but we are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.
If you choose to temporarily disable antispyware or antivirus software before you install Internet Explorer 11, follow these steps:
- Turn on Windows Firewall.
