I install my EF5 winforms application using Click Once.
When I installed on a Windows 7 virtual computer it worked correctly, however when I installed on a Windows XP virtual computer I got an "underlying provider failed on open" error.
I consulted this link and decided to look at the Distributed Transaction Coordinator in component services on the XP computer..
I only viewed things in component services, by expanding the tree. Now my application works, and I don't understand why it didn't or why it is fixed. Can anyone explain this to me?
