But I managed to do it with the following Post:
https://stackoverflow.com/questions/182750/map-a-network-drive-to-be-used-by-a-service
I found a slightly easier way to do this. If you share the computer with another user than this wont work well but if this is a single computer with only one user with admin rights than this works.
First issue is credentials so you want to open start menu and type services.msc to open the service manager
find and double click EABackgroundService click on the logon tab and change from local system account to this account enter your current user account and password and click ok this will ensure the EABackgroundService runs under your user account instead of system allowing it to access your saved network credentials
The next part is a bit different because I found the app seems to have issues with mapped network drives and not network locations so to work around this map the network drive but when you set your download location do not use the mapped drive instead at the bottom of the folder selector enter the full path to the network location
The origin app cannot navigate a mapped network drive by default but if you set your download location directly using the server and share name it will work without an issue. You do need to have the drive mapped so that the credentials are available to your user account
on a side note I created a user account on the server with the same username and password as the laptop and assigned that account permission to the desired shares which makes mapping the drive a bit easier I do not know if this is needed to make it work but figured I would mention this in case my work around does not work without this setup.
I wont go into details here because I figure if you are the type of person running games off a NAS you already know how to set up accounts and assign share permissions
