Both the PDF app and PDF documents do not open up
Hello, I have tried to open today several pdf documents as well as the Acrobat rdeader app and they all fail. I get error messages saying that Windows cannot find my docs in C:.... indicating the folder and my document. I contacted Microsoft and they uninstalled Windows 10 and reinstalled it successfully with all updates. I have also uninstalled and installed again Acrobat reader. The same problem persists. I cannot have any other solution to this problem. Please help. It is urgent! Many thanks
