Query error on OLEDB linked server working in SQL Server 2012

Hello.
I linked server to the iHOLEDB.iHistorian provider with sql server 2012 and Proficy Historian 5.5. Proficy Historian and sql server are on the same physical server.
The test of connectivity is OK but my query return systematicaly the errors:

Msg*7399
The provider OLE DB "iHOLEDB.iHistorian" of linked server "ihistorian" reported an error. Acces denied.
Msg 7350
Impossible to obtain the information of column from the provider OLE DB "iHOLEDB.iHistorian" to linked server "iHistorian".

Here my linked server:

/****** Object: LinkedServer [iHistorian] Script Date: 01/04/2015 13:06:28 ******/
EXEC master.dbo.sp_addlinkedserver @server = N'iHistorian', @srvproduct=N'Proficy Historian', @provider=N'iHOLEDB.iHistorian', @datasrc=N'servsql3'

Here my query:

select timestamp, tagname, value, quality from openquery (ihistorian,'SELECT * FROM ihRawData
WHERE samplingmode=rawbytime
AND Quality NOT LIKE "good*"
AND tagname = FIX.ADV/CSP030-FR-001.F_CV
AND timestamp>=Now-24H') ;

I have already looked at the links of the forum on the subject...

Thank you for your help
