Hi Arch
Make sure you use a registry cleaner before any downloading or re-installing.
Re-boot your system.

Quite often folders are left behind containing data that are not part of the uninstalling process.
Check around by using the search tool (File Explorer for Win10).
There is no reason why a new or re-installation should cause problems unless
your Steam downloads are causing a conflict.
Check your Program Files (x86) folder to see what is going on.
