A family of Microsoft word processing software products for creating web, email, and print documents.
Uninstalling and reinstalling Office is going to have absolutely no impact on the problem of a document that has become corrupted because it was saved to a USB drive. Also, scanning the USB drive will be of no benefit as the problem is not with the USB drive itself, but with the fact that Word documents should NOT be saved directly to a USB drive.
If the document is not too large to attach to an email message, send me a copy of it that way, referencing this thread in the covering email message and I will see if I can recover anything from your document.
Alternatively, upload a copy of the document to the following folder of my OneDrive

and send me an email to the address shown in my signature to let me know that it is there.
