For me normal.dot was not the cause of the problem. Here is a bit more background:
Not sure if needed in this context, but I always use a file manager configured to show system and hidden files.
Windows 10 machine, fully updated
Microsoft® Word for Microsoft 365 MSO (Version 2306 Build 16.0.16529.20164) 64-bit
- Close Word and any app that may be using Word (e.g. Outlook).
- Find the QuickStyles folder. On my machine it is here:
C:\Program Files\Microsoft Office\root\Office16\1033\QuickStyles
- Locate basicsimple.dotx in the folder
- Move the template to another folder (or delete if you feel bold)
Hope this helps
The location for Custom [Quick] Style Sets is:
C:\Users*username*\AppData\Roaming\Microsoft\QuickStyles
Look there first.
For versions of Word earlier that 2016, the location for the installed ones will be in a different folder than used by ITMgr101.
Off-topic Jargon alert:
It is Normal.dotm, not Normal.dot nor Normal.dotx.
Normal.dot was for pre-Word 2007 systems. Those systems would not be using [Quick] Style Sets.
Normal.dotx has never been a part of a Word installation. The normal template is always macro-enabled.
