When you use the Thinkwise Deployment Center for the upgrade of a new released IAM-version the deployment center is asking to specify the application folder path and the path for linking the IAM files (for example: Images and Reports).
In the manual there is no explanation how you need to define the correct path. When you give the wrong network path the deployment center will automatically create a new folder with his subfolders.

Up to what level do you need to specify these folder path?
For example:
....\Software_Factory\Application\
....\Software_Factory\Application\SQLSERVER_IAM\
....\Software_Factory\Application\SQLSERVER_IAM\2018.3\
