NOTE:  If using the Microsoft Edge browser, users will require updating their browser settings>>>>select [Settings]>>>>then [Cookies and Site Permissions]>>>>review right-side navigation and locate/select [PDF Documents]>>>>then toggle [Always Download PDF Files].  Microsoft Edge is defaulted by MCEN network administrators with automatic settings to open in your browser and by doing this it will encounter a permissions issue to open file rendering it not readable which will engage you to change to Acrobat Reader as a default for opening PDF files from your computer (right click PDF file; choose [Open With]; then select [Another App]; select [Adobe Acrobat Reader DC].  This in-turn should allow the file to be "Save As" and opened in its orginal state via the application on your computer.  Please be advised!
