When you start Cover as an administrator and/or via a CoverSwitch, the network drives configured in your profile are not defined in the administrator profile.
When you start Cover under these conditions, you will receive a message of this type:
Rather than using a network drive, use the absolute address corresponding to it, which will be recognised by all the profiles with sufficient rights, as the administrators normally have them all).
For example, replace the path G:\Cover\Data\Projects connecting you to the Cover\Data\Projects directory located on the "DATA" share of a "SERVER_ENTREPRISE" server by its equivalent in absolute path \SERVER_ENTREPRISE\DATA\Cover\Data\Projects.
