Using addons - Healix/Gw2Launcher GitHub Wiki

To use different addons per account, localized execution (Settings > Guild Wars 2 > Management) must be enabled. This will effectively give each account its own copy of the Guild Wars 2 folder, which can be found under Guild Wars 2/Gw2Launcher/#, where the ID # can be found by right clicking an account > Edit > Statistics. Note the account has to be launched once before the folder is created. These folders can be deleted to automatically recreate them on the next launch.

Using the same addons for every account

By default, addons stored in the original folder will be automatically copied to each account when the account's folder is created. Localized execution can also be configured to keep addons synchronized with the original folder, where any changes to the original will apply to all accounts.

Using addons on only one account

Localized execution can be configured to include/exclude accounts. If you only want addons on 1 account, choose to only include 1 account, then place addons exclusively into the folder for that account.
