Installing Localized Versions of Dotnetfx.exe Windows 98 or Windows ME
When installing the .NET Framework redistributable package, Dotnetfx.exe, on a computer running the Windows 98 or WindowsMe operating system, the system code page and font need to support the language of the dotnetfx.exe being installed. There are several options:
- Install the same language of dotnetfx.exe as the language of Windows 98. For example, install Japanese dotnetfx.exe on Japanese Windows 98.
- Install a localized version of dotnetfx.exe onto a localized Windows 98, in which the system code page is the same for both languages. For example, install French dotnetfx.exe on German Windows98.
- Install English dotnetfx.exe onto any localized Windows 98.If the system code page and font do not support the language of the dotnetfx.exe being installed, then dialogs will not display correctly. For example, when installing the Japanese dotnetfx.exe onto English Windows98, setup dialogs will not display text correctly.
This limitation only applies to Windows 98 and WindowsMe. You can install any language version of Dotnetfx.exe on any language version of Windows 2000, Windows NT 4.0, Windows XP, or the Windows .NET Server family.
