Installation
Q: We are sharing Photopia on a network and some
of the client computers get a blank screen when viewing the
Layers screen.
A: The Layers screen, Preferences screen
and the Property control on the right side of the screen
all require that a particular DLL be installed on the computer.
The particular DLL required is commonly used by other software
and is sometimes already on the system. If the screens mentioned
above are blank however, then this DLL is not present on
the system and needs to be installed. It can be installed
by running the Client Installation option from the LT Product
CD.
Licensing
Q:
We have Photopia shared on a network and would like
to add a new client computer. What do we need to do?
A: 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.
Q:
When I try and get the Site Code to send in for authorization,
I get the following message: “Unable to create
site code for client computer!”
A: 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.
Q:
Photopia has already been licensed on our computer, but
when we log in with a new user account the license is
not found and we cannot open a project in Photopia?
A: 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.
Q:
We have Photopia setup to be shared across our network.
Our clients were working fine but now are unable to access
Photopia and get a “network timeout error.”
A: 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
\LTI\Photopia2\Exe\PhotopiaPODT.nwk
Q:
We are setting up Photopia on a network but when the
clients try and access Photopia they get the following
error: "Unable to connect to server for authorization."
A: 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.
