Failed to install .NET Framework 4.5.2 Japanese language pack on Windows 8.1 (English) RRS feed

  • Question

  • Failed to install .NET Framework 4.5.2 Japanese language pack on English version of Windows 8.1.

    I changed UI language to Japanese from English in Control panel on Win8.1. Then, I installed .NET Framework Japanese language pack.

    However, the installer stopped installation and shows messages like an "Unsupported environment".

    Is there any way to install Japanese language pack?

  • Hi いとけん-san,

    Not sure which .NET framework version on your existing system as Windows 8.1 might have build-in upper .NET framework version. So please go to Control Panel\Program and Features\Turn Windows features on or off to check if you have upper .NET framework version installed or ticked. 

    Here is the official article about installation caution. Please check it and make sure you not have similar scenario on your system.

    All .NET Framework versions since .NET Framework 4 are in-place updates, so only a single 4.x version can be present on a system. In addition, particular versions of the .NET Framework are pre-installed on some versions of the Windows operating system. This means that:

    If there's a later 4.x version installed on the machine already, you can't install a previous 4.x version.
    If the OS comes pre-installed with a particular .NET Framework version, you can't install a previous 4.x version on the same machine.

    If you install a later version, you don't have to first uninstall the previous version. 

    For more information, please refer to : .NET Framework system requirements
