Check first that you can open a Vault GUI client and log in. Does that work?

The error you are showing me usually shows up when the bitness of the application pools doesn't match the version of Vault installed; 32-bit versus 64-bit.

[gregch]

yes it works
Client is 64 bit

[Beth]

The error that is in the first post is a server side error.

Are you trying to connect to a different server with VS than with the client?

[gregch]

Yes, it is server side, but the error message is complaining about assembly framework mismatches. This is a local machine, only one server

I did install VS 2015, I don't if modified some core assemblies

[Beth]

Was Vault installed after Visual Studio?

Can you check that you installed the right version of Vault? (Vault Standard versus Vault Professional is what I'm looking for.)
