Could not obtain a required interface error

I have created a linked server that connects to "mpp" file, and it connects and opens successfuly returning a list of tables that exists in the linked server to the mpp file.

But the problem i am facing now that whne i write a select statment to get data from the tables in this linked server

select * from linktompp.testmpp.dbo.tasks

such that linktompp is the linked server name

testmpp is the catalog name

tasks is the table name i need to select data from

it shows an error that says

"Could not obtain a required interface from OLE DB provider 'Microsoft.Project.OleDB.11.0'."

"[OLE/DB Provider 'Microsoft.Project.OleDB.11.0' IUnknown::QueryInterface returned 0x80004002: IGetDataSource]"

could anyone tell me the reason of this error

thanks
