latex/ctex运行中文模板报错expl3 primitives not found

为了写论文要用latex,但是根本不懂,我用的是ctex+miktex+winedt10.3,
运行各种中文论文模板后总是出现这个报错

AppData\Local\Programs\MiKTeX 2.9\tex/latex\l3kernel\expl3
-code.tex"

! Package expl3 Error: Required primitives not found.

See the expl3 package documentation for explanation.
Type H for immediate help.

球球各位了,很急
(不要问我为什么乱打标签因为没有latex标签又不能自己打标签我也很痛苦)
