This is really weird. I have uninstalled and installed the Firebird client 4.6.1.0 and the DDEXProvider 3.0.1.0. I have also used the nuget to install firebird into the solution. If I try to edit my existing connection string in the Settings I get an error "Unable to find the Requested .Net Framework Data Provider. It may not be installed."  If I attempt to add a connection to the server explorer I can get the add connection form but I cannot fill in the required information. The Firebird Data Source is listed next to the change box. If I start to type in the Data Source text box the form closes. I can launch the project and it will work. I just cannot add or edit anything in any dataset created earlier. Has anyone experienced this and what steps resolved it.

It has been quite a while since I have worked with Firebird, so please be patient, whilst I cull my memory banks...

As a test, I installed Firebird using the Nuget package.   What update are you using with Visual Studio 2013 (I am using Update 4)?

I figured it out. For some weird reason the Firebird DDEX will install multiple times in the Machine.config file. I removed all but one and it works. This has happened again after the fix and when I checked the Machine.config file it had two more instances of Firebird in there again. So apparently something is buggy with the installer whereby it does not recognize that there is already an entry. Everytime I create a new project and add the Firebird resource it appears to add another instance in the Machine.config.

So for everyone else out there reading this, just open the Machine.config file in your .Net folder and delete the multiple lines referencing Firebird leaving one reference. Then you have to reboot your computer to make sure it takes affect.
