LaTeX Error: File `l3regex.sty' not found

For TWMS Journal of Applied and Engineering Mathematics (TWMS J. of Apl. & Eng. Math.) Journal, I downloaded Latex template. If I run the file using Winedt 10.2, I am getting "LaTeX Error: File `l3regex.sty’ not found" error. I Updated both MikTex and WinEdt. But still its showing same error.
