Vortex

Portable install

Vortex can be started in "portable" mode by starting an instance in "shared mode" and using CLI arguments to specify the data path. A shortcut to a launch a portable Vortex instance would look like

S:\Programs\Modding\Vortex\Vortex.exe --shared --user-data "S:\ProgramData\Vortex\UserData"

However, when clicking on "Download with Mod Manager" links from Nexus, if the portable instance is not launched, the download might start in an instance started without using these CLI arguments.

To fix this one need to use NXMProxy which allows to forwards download links to different mod managers and to configure command line arguments when starting Vortex by downloading. Unfortunately it requires to disable the Vortex pipe which still use vanilla Vortex:

# %LOCALAPPDATA%\nxmproxy\config.toml

[games]
_ = "Vortex"
skyrimspecialedition = "MO2SSE"

[managers]
Vortex = '"S:\Programs\Modding\Vortex\Vortex.exe" --shared --user-data "S:\ProgramData\Vortex\UserData" --download %1'
MO2SSE = '"S:\Programs\Modding\MO2SSE\ModOrganizer.exe" %1'

[pipes]
# Vortex = vortex_pipe # <-- Delete this
