Photopia Licensing Support

Adding a new network client

For Version 3.0, simply run the Photopia.msi installation on the client, choosing the Client Installation option and then browsing to the share on the server that has a path similar to \\servername\Photopia3\. There are additional steps for Version 2.0. First, run the client installation option from the CD on the client computer. You then need to run the PhotopiaReg.exe program. Log into the client computer with the user account for the person who will be using Photopia. From Windows Explorer, navigate to the server computer over your network and go into the \LTI\Photopia2\Exe shared folder on the server and run PhotopiaReg.exe by double clicking on it. PhotopiaReg.exe will ask you to locate Photopia.exe on the serving computer. Click the Browse button. Be sure that the file dialog is viewing the \LTI\Photopia2\Exe folder on the server, not a local drive. If it is not, then navigate to it. Once you are in the correct folder, then select Photopia.exe. Once finished, close PhotopiaReg. You should now have a shortcut added to your desktop to Photopia.exe on the server. Double click the shortcut and you should now have access to Photopia on this client.

Switching Users on a computer

Photopia requires some path information to be stored in the system registry under each user’s local settings. So whenever you need access to Photopia for a new user, you need to run the PhotopiaReg.exe program while logged in under the new user’s account. From Windows Explorer, go into the \LTI\Photopia2\Exe folder and run PhotopiaReg.exe. PhotopiaReg.exe will ask you to locate Photopia.exe on the serving computer. In this case, your computer is the “serving” computer. Click the Browse button. Locate and select Photopia.exe in the default folder that is opened in the file dialog. Once finished, close PhotopiaReg.

"Unable to create site code for client computer!"

If you have installed under a different user account than your personal user account (Administrator, for example), then you will need to run PhotopiaReg.exe once you log in under your personal account. This will properly setup the registry under your local user settings. From Windows Explorer, go into the \LTI\Photopia2\Exe folder and run PhotopiaReg.exe. PhotopiaReg.exe will ask you to locate Photopia.exe on the serving computer. In this case, your computer is the “serving” computer. Click the Browse button. Locate and select Photopia.exe in the default folder that is opened in the file dialog. Once finished, close PhotopiaReg.

"Network Timeout Error"

If access is ever denied to a client trying to access the shared copy of Photopia and if it is certain that the number of licenses you own are not already being used by other clients, then there is probably an old copy of a client log file on the server. The client log files are created by each client when using the program and are supposed to be deleted when they exit Photopia. Sometimes however, these files are not deleted by the client and need to be manually cleaned up. This could happen if the network connection was lost or if the client did not close properly, for example. To reset these files and free up access to all client computers again, delete the following files from the server:

\LTI\Photopia2\Exe\Photopia.nwk -or- \LTI\Photopia3\Exe\Photopia.nwk

\LTI\Photopia2\Exe\PhotopiaPODT.nwk -or- \LTI\Photopia3\Exe\PhotopiaPODT.nwk

"Unable to connect to server for authorization."

This error is seen when the client computer does not have read access into the appropriate part of the system registry on the server computer. See the instructions for your specific server operating system in Chapter 2 of the User’s Guide for details on how to setup read access permission for all of the users that need to run Photopia. If you have already done this and if your server is running Windows XP Pro, then see the additional information that follows as you might need to setup some additional permissions. The instructions in the User's Guide tell you to set read access permissions for the Photopia users on the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurePipeServers\winreg

This key allows those users to remotely connect to the server's registry, but does not necessarily give permissions to read all of the keys within the registry. If your clients get the error message listed above, then they are not getting the necessary read access rights to the particular key in the registry where the licensing information is stored. To add the necessary permissions, you need to set the read access rights for either Everyone or just the group of users that will be using Photopia on each of the keys in the following path:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID

This means that you need to select each of these keys individually, then right click your mouse and choose Permissions from the pop-up menu, then set the read access permission.
