SNAOLEDB Fails with "Data conversion (DCONV.DLL) not found" Error Message

ID: Q196946

The information in this article applies to:

Microsoft SNA Server, versions 4.0, 4.0 SP1
Microsoft OLE DB Provider for AS/400 and VSAM, version 1.0

SYMPTOMS

Attempts to initialize the SNA Server OLE DB Provider for AS/400 or VSAM (SNAOLEDB) may fail with the following error message:

Data conversion (DCONV.DLL) not found

This error may occur even though the Dconv.dll is present in the <snaroot>\System directory.

CAUSE

The SNA Server Dconv.dll is dependent upon the SNA Server version of Trnsdt.dll which SNA Server installs into the <sna>\System directory. If IBM Client Access is also installed on the computer, it installs its own version of Trnsdt.dll which conflicts with the SNA Server version, causing Dconv.dll to fail to initialize.

This problem may occur with any version of the SNAOLEDB driver.

RESOLUTION

To solve the problem, rename the version of Trnsdt.dll located in the IBM Client Access directory, if it is installed on the computer. Only the SNA Server version of Trnsdt.dll should be present on the computer.

NOTE: Renaming the IBM version of Trnsdt.dll may cause IBM Client Access applications to fail.

If there are no duplicate versions of Trnsdt.dll present on the computer, ensure that there are no conflicting versions of these other dependent DLLs, and that these are available in the system path:

Shipped with SNA Server:
