I did the upgrade and the deployments are still not working from the previous configurations. i think this update only tried to fix the permissions on the default package share.
my initial setup that worked great for years is something like this: lansweeper server named Inventory1 and file server named FileShare1
FilesShare1 has a folder shared out to all domain users called Files. so \\fileshares1\files
server Inventory1 will not deploy anything that points to FileShares1
but if i created the same Files folder and share it out with the same permissions on Inventory1 as Antony_S may have suggested as a test before, this does work. i have no tried any other servers but may try that today. i do have a support case open and have sent them debugging logs but have not had success.
