Orion NPM v10 to v11.5

Hello all,

I have determined the upgrade path and downloaded the appropriate version to reach 11.5, however when I go to install the "next" version, it prompts: Orion Network Performance Monitor is already installed.  To repair this installation, use the "Add or Remove Programs" control panel.

I do have the SolarWinds-Orion-v10.1.3-Full     ... I did not see a -Upgrade  

Will I need to uninstall the current version and install the 10.1.3?

Best,
