CAUSE

Comcat.dll has not been registered properly or an incorrect version of the Comcat.dll file has been installed.

There are two versions of this DLL:

Version 4.71: 22 KB (Correct version)
Version 5.00: 6 KB (Incorrect version)

First, try registering the Comcat.dll file that you currently have on your system. To do this, on the Start menu, click Run, and type regsvr32 Comcat.dll. Also register the following DTS files:

Dtspkg.dll
Dtspump.dll
Dtsffile.dll
Dtsui.dll

If you continue to see the error, follow these steps to replace Comcat.dll version 5.0 with version 4.71:

Unregister Comcat.dll version 5.0. To do this, on the Start menu, click Run, and type regsvr32 /u Comcat.dll.
Delete or rename the incorrect Comcat.dll file, which is located in your [windir]/system[32] directory.
Copy Comcat.dll version 4.71 version from the the x86\System directory of the SQL Server 7.0 CD to your [windir]/system[32] directory.
Register version 4.71. To do this, on the Start menu, click Run, and type regsvr32 Comcat.dll.
