You want to update some files that live in the uses' profiles on target machines and would like to know whether it is possible to do this by using the ‘Deploy Custom Software’ function.
Unfortunately, this is not possible to accomplish using LanGuard. LanGuard utilizes an administrator account to log in and perform operations, and any executed by Deploying Custom Software custom script that is utilizing %APPDATA% or %USERPROFILE% environment variables would refer to this account, not the actual users using the machine. Moreover, there could be multiple user profiles on client machines as Windows create a new profile for each new logon.
Usually, the described task can be accomplished with Windows group policies, which is out of scope for LanGuard's support.
