Illustrator designated as installed, but isn't on computer?

About 20 or so days back, I installed Adobe Illustrator onto my computer. I opened it, and it worked just fine. Since then, I've been using Illustrator on my classroom computer, with no reason to open it on my home computer until now. I went to run it a few minutes ago, only to find it was apparently no longer installed on my computer. This would be an easy fix, except for the fact that, according to my Creative Cloud software, it is, in fact, still installed. I've checked my program folder and ran a search with no luck. Any idea on how I might resolve this?

I'm on a Fujitsu Lifebook T734, running Windows 7 Professional 64-bit OS, if that helps at all.
