api-ms-win-core-rtlsupport-l1-2-0.dll Missing

[STYeung]

Hi Tete,

When I start the firefox (firefox-53.0.3-2017051800) program, it always popup a error message (The meaning is it cannot find api-ms-win-core-rtlsupport-l1-2-0.dll). Could you help !.

Also, Is your private builds (Win32) of Mozilla Firefox 53 support window-XP platform ?

Thank you
– ST Yeung

Hello STYeung,

Thank you for reporting the problem. I updated my build.

Also, my custom Firefox 53 do not support Windows XP/Vista like an official Firefox 53.

Hi STYeung,
As you probably know, Firefox 53 and later does not support Windows XP / Vista even in official builds.
It also has an announcement on the official FAQ below.

STYeung さん，
ご存知かとは思いますが，Firefox 53 以降では公式のビルドでも Windows XP/Vista をサポートしていません。
それは，下記の公式 FAQ にも案内があります。
