Re: can't run word

With /a or /safe (I don't understand the finer details of the difference) it's run without add-ons. Check those.

What's in the Word Startup folder? That contains things Word opens at startup. Something strange there and you get the symptoms you see.

Also make a new Windows account and try there. If it works OK there, it's some setting or file in your account. If it doesn't work there either it's on system level. Knowing such helps find it.
