PRB: CdoE_NO_SUPPORT at CDO Logon

ID: Q244547

The information in this article applies to:

Collaboration Data Objects (CDO), version 1.21

SYMPTOMS

An application using CDO may work on some systems but fails on others with the error "CdoE_NO_SUPPORT" (error code 80040102).

CAUSE

The CDO DLL installed on the target system may not be the correct DLL for the Windows platform on which you are running it.

Some CDO (version 1.21) builds are inaccurately labeled for both Windows 9x as well as Windows NT in the description information of the file properties. This is inaccurate; CDO version 1.21 is platform specific. There are two different versions: one for Windows 9x systems and one for Windows NT systems.

RESOLUTION

Microsoft makes available free downloads of platform specific versions of CDO (that are correctly titled in the description.) See the following article to get these versions of CDO:

Q171440 Where to Acquire the Collaboration data Objects Libraries

Note however that these versions may have a lower version stamp than what is already installed on your system. Therefore, in order to successfully install the download, you may need to rename your existing CDO.dll.
