Am setting up UPK 11.1 on a laptop (document library will be there). When I start up the Developer client, the system prompts for the address of the library. It is on the C drive of the PC, but when I enter the path to the library, I see an "Invalid Location Format" error. I have set UPK up on a laptop before; I just can not remember how to locate the spot for the library on the PC.
This may be an extremely asinine question, but which installation option did you select when installing UPK 11.1 on your laptop?
There are 4 options (applicable to developer other than Knowledge Center) and some people do confuse them sometimes:
1. Developer Client
3. Server and Client
4. Single User Install
You should be selecting option 4 - Single User Install. To me, it sounds like you installed the Developer Client (which is used in multi-user environments) to connect to a UPK server (where the library resides on the database).
When UPK asks you for the library location, does it gove you an example of the format it requires (i.e. https://server/virtual directory)? If this is the case, then you most certainly have the incorrect "developer" option installed. When creating a new profile in UPK, you are requested to define the library location (whether in a single or multi-user environment). For a single environment you can define any local folder, and for a multi-user install, you will define the virtual directory as defined in the server installation of UPK.
Try and re-install using the Single User Install option and see how it goes?
