Just FYI for anyone facing this issue:

I was facing an issue when trying to install DDM (version 2.3) on my fresh Windows 11 PC and getting an error that I already have a newer version installed (I hadn't installed it!)

To get around this, I installed the latest Dell Display and Peripheral Manager, and uninstalled it through revo uninstaller (medium scan and removal).

Thereafter I was able to install DDM (version 2.3).
