URGENT NEED FOR lost MS Excel setup file; Email or download file? [see details]?

I had an MS Office suite (old, but legit) on my computer %26amp; was using Excel to help me manage my mom's diabetes, keep track of her feeding, medication, bathing, and other healthcare %26amp; lifesaving efforts I and my dad use in caring for her (she's a constant care patient at home).





My computer became slow, so I deleted a lot of files and cleaned up the HDD (avoiding removal of Excel, etc.) -- but while I was working in the wee hours of the morning (I've probably averaged 3-4 hours of sleep per day for the past month since Mom last got back from the hospital), I noticed my MS applications were in separate folders.





For whatever reason, this bothered me, and I tried moving all of them into a new "Microsoft" folder. I ignored the "this may cause some applications to not work" message, because it had always been overly cautious (apps always seemed to continue working normally) in the past, plus I was really fatigued and didn't appreciate the significance of the message.
