error when export excel file to sql server using c#

Hi friends

I am using
Visual studio 2010
sql server 2008 (64 bit)
ms office 2007 (32 bit)
The following is my sql queries

ALTER procedure [dbo].[sp_excelforgeneralholidays](@filname nvarchar(max),@getdate datetime,@adminid int)

begin

declare @datavar nvarchar(max)

declare @sql varchar(1000)

--set @getdate=coalesce(@getdate,Getdate())

set @datavar = 'Excel 12.0;Database=' + @filname

set nocount on

--create table #temptable (Date date ,Day varchar(30),Reason varchar(100))

set @sql ='insert into Generalholyday_details(Date,Day,Reason) SELECT * FROM OPENROWSET(''Microsoft.ACE.OLEDB.12.0'','''+@datavar+';HDR=YES'',''SELECT Date,Day,Reason FROM [Sheet1$]'')'

exec (@sql)

update Generalholyday_details set createddatetime= @getdate where createddatetime is null

update Generalholyday_details set adminid=@adminid where adminid is null

end

the following error appears

OLE DB provider 'Microsoft.ACE.OLEDB.12.0' cannot be used for distributed queries because the provider is configured to run in single-threaded apartment mode

I changed the following also, but still error occurs

exec sp_configure 'show advanced options', 1  reconfigure  GO  exec sp_configure 'Ad Hoc Distributed Queries', 1  reconfigure
