SanDisk Flash Memory missing on Dell laptop

Does anyone actually know how to trigger a reactivation? I haven't done anything out of the ordinary here. I was just working on a document in LibreOffice, printed it a few times, and then the printer started jamming, distorting the colors, and eventually just gave up. I checked the hardware itself—it claims everything is fine—but then this error pops up saying the SanDisk Flash Memory isn't installed.
I’ve tried everything within my limited toolkit. I attempted a system restore to an earlier date, but the computer refuses. I tried to reinstall the SanDisk Flash Memory, and again, it won't let me. I went hunting for drivers online, found some stuff on a Dell support page, but I can't make head or tail of the download process. There are files for everything else, yet nothing specifically for what I need.
Is there a straightforward way to fix this? It doesn't even have to be easy; I just need some actual direction to follow.

Is this laptop running Windows Vista or Windows XP? The driver page only supports those two operating systems.

Take a look here; apparently, the card reader driver (ENE Card Bus Driver) fixes the issue. 🤷

(Unzip the folder and run Setup.exe)

I can't do that; I'm stuck on Windows 7

Did you try pulling the driver through Windows Update? Does Dell even offer some kind of dedicated utility for their drivers?

P.S. Give the Windows Vista driver a shot.
