Can we change the install (deployment) location to the all Users shared profile?
Oracle Service Cloud (OSvC), All supported versions
It is not possible to change the install or deployment location to the All Users shared profile.
The OSvC application is deployed via Microsoft's ClickOnce Technology. Applications deployed via the ClickOnce mechanism are specific to the user and by default all application components are deployed in the Windows Profile. Deployment of the OSvC application can not be shared among users by deploying to the Windows All Users profile.
Deployment options are available which may address your concerns. For information on deployment options for the OSvC application, please see the Deployment Guide for you version of the OSvC application. Version documentation is available in Answer ID 5168: Documentation for Oracle Service Cloud Products.
