word, excel, mail merge

It is looking for a file in the Office 16 folder. Do you have 2 versions of Office installed.?

I have done simple Mail Merges on this machine here without issue using Office 2016 (machine never had anything earlier on it). I used Excel addresses and Word Letter.

and you do have one Office in 32-bit and another one in 64-bit? some required libraries are not compatible when this situation happened.

That would certainly be true if both bit-strengths were installed. I would not expect Office 2010 to be 64-bit but Office 2016 could be. The one version should be removed if present

At this point, uninstall Office 2010, restart, install it and update it and see if that works.

@pramod1 As what @John has mentioned, please try to reinstall or repair Office as suggested. You may refer to the link below for step by step instructions on how to repair Office. Please carry out the online repair.

Did you have another office version on this system at some point? There could be some element that did not uninstall properly and has caused a conflict with the 2010 version.

Given that fact, as John said it is probably best to uninstall and reinstall. The uninstall step is important as you want to be sure to catch any files that were replaced by 2016.

After that it may become a case of diminishing returns. Either take more time to troubleshoot, or wipe the system and reinstall Windows.

Thank you and I trust Office is now working for you.
