Unless you have Photshop Elements or Premiere Elements 2020 installed, I think that the Acrobat Elements that you're referring to a file called "elements.exe" which belongs to the Adobe Acrobat Distiller.
As far as having Adobe Acrobat installed into two separate hard drive partitions doesn't make sense. Looks to me that this happened after an update or something. In a MS Windows box the default installation drive always starts in C:\ where the Program Files and Program Files(x86) are called from after a successful installation.
You shouldn't mess with the DLLs that you're talking about, and reinstalling shouldn't be necessary either.
I would say to clik on Help--->>> "Repair Instalaltion". This procedure is entirely different than reinstalling on top of a defective old installation, and also different from uninstall/reinstall.
When you choose Repair Installation, pay close attention to where the Acrobat components are installed by default rather than manually selecting a different separate partition to install the program. That is unless you're running out of space in your C:\ partition then it would make sense.
BONUS TIP: If having two separate partitions is what you want, is better if you use an entire hard drive just for the operating system and installing the programs that will be used by Windows. Then on a separate different hard drive you can move all your data folders, such as MyDocuments, Downloads, etc. to that hard drvie partition.
If at some point your C:\\ drive crashes, for example, or it becomes corrupt, you won't loose your valuable documents and other important data. And when it comes to troubleshooting you'll only need to erase and reinstall the OS in that drive and programs without worrying about loosing anything. This makes your computer work slightly faster too.
