There are some locations in which Microsoft Word does not permit drawing objects.

We thought we had most of them detected, it seems you have found another.

Please can you supply us with a sample document showing clearly where chem4word is unable to insert or update structures? You can either send them to info@chem4word.co.uk or post them on our facebook group at https://www.facebook.com/chem4word

We have developed a PowerShell script which can detect all installations of Word which you have on your machine it can be found at https://pastebin.com/k7tw8eZn

If any of the detected installations are in a folder that starts with “C:\Program Files\WindowsApps” this indicates that they have been installed from the Microsoft store and should be uninstalled and replaced with the normal ClickToRun installed which you can find at https://portal.office.com/account or https://www.office.com

NB: “C:\Program Files” is windows installation language specific an may vary
