The 问题

Word crashes on startup or refuses to 打开, but you’re unable to launch it even in Safe Mode to isolate add-ins. Or Safe Mode works, but when you return to normal mode, the 问题 persists. Safe Mode is typically used to 排除故障, but when that fails too, the 问题 is severe.

2. Type: "C:\Program Files\Microsoft Office\root\Office16\WINWORD.EXE" /safe and press Enter

Force Safe Mode launch (Mac):

1. Quit Word completely
2. 打开 Terminal (Applications > Utilities > Terminal)

5. Disabled items accumulation — Too many disabled items prevent launching
6. System-level conflicts — Windows system issues (not just Word)
7. Incomplete Office installation — Initial installation corrupted or interrupted
8. Profile corruption — User profile prevents Safe Mode from loading properly
