Getting a licensing error when running program under XP
Posted: Thu 01 Dec 2011 22:14
I'm working on a program that will run as a Windows service and needs to access a PostgreSql database using entity framework.
I am developing on Windows 7 using MS Visual Studio 2010. Everything works fine when I run the application on my workstation. In fact, I'm extremely happy with the way everything is running on this machine.
I need to test this any my other WPF application on XP -- They work together. I copied the executables and config files onto a thumbdrive and then copied them onto the XP machine. When I start the windows service program, I'm getting the following error in the event log:
I boned up on the licensing topic in the documentation and I added a license.licx file to the LPRCore.exe program. I checked the executable using .NET Reflector & I can see the file's contents embedded in the LPRCore.exe's resources. But I'm still gettign this error on the XP machine.
What do I have to do to make this work?
Regarding my WPF program:
I am now getting the following message when this program first tries to retrieve data from the PostgreSql database ON THE SAME XP MACHINE:
The Devart DLLs are used by a class library and the ones it references are the versions from the September release (Devart.Data.PostgreSql Version 5.50.214.0).
I have even deleted the references to the Devart DLLs and added them back into the DLL with no difference. Everything runs fine on my development workstation but I get the same error about the wrong DLL version on XP.
Here is the contents of the licenses.licx file in this class library:
What is causing this issue?
