Question

I want to execute simple statement:

SELECT * FROM 
OPENROWSET('MICROSOFT.JET.OLEDB.4.0','Text;Database=C:\Temp\;','SELECT * FROM [test.csv]')

And suddenly I get this message today morning:

Msg 7308, Level 16, State 1, Line 1
OLE DB provider 'MICROSOFT.JET.OLEDB.4.0' cannot be used for distributed queries because the provider is configured to run in single-threaded apartment mode.

It was working till today morning!

Here is my server specs:
Windows 2008 R2 64 bit
SQL Server 2008 64 bit

I’ve installed AccessDatabaseEngine_x64.exe.

Sql Server is running under LocalService account.
I’ve set Everyone to have FullControl permission to “C:\Temp” as well as “C:\Windows\ServiceProfiles\LocalService\AppData\Local”.

Is there anything I missed? I’m really confused…

Edited:
I’ve also executed these statements:

sp_configure ‘show advanced options’, 1;
 GO
 RECONFIGURE;
 GO
 sp_configure ‘Ad Hoc Distributed Queries’, 1;
 GO
 RECONFIGURE;
 GO

EXEC master.dbo.sp_MSset_oledb_prop N’Microsoft.ACE.OLEDB.12.0′, N’AllowInProcess’, 1
 GO
 EXEC master.dbo.sp_MSset_oledb_prop N’Microsoft.ACE.OLEDB.12.0′, N’DynamicParameters’, 1
 GO

I’ve also tested ACE.OLEDB.12.0 with administrator account:

SELECT * FROM  
OPENROWSET('MICROSOFT.ACE.OLEDB.12.0','Text;Database=C:\Temp\;','SELECT * FROM [test.csv]')

There is another error:

OLE DB provider "MICROSOFT.ACE.OLEDB.12.0" for linked server "(null)" returned message "Unspecified error".
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "MICROSOFT.ACE.OLEDB.12.0" for linked server "(null)".

Finally I found it:
I ran ProcMon and I saw that Sql Server wants to access to F:\Windows Temp\ and the folder does not exist! I created the folder and the issue is solved. But, I never had such a folder!!!
