>>The placement of the dll is established by installshield as the default location. This file is installed as a C runtime merge module. I have not specified where to put it. In fact, there is no way to specify a location (other than to distribute it as an external file). There are about 2 dozen copies of this file on my development PC most of which are in application specific folders.

The subject file is already in the winnt\system32 folder on the win2000 PC. Windows will not allow it to be overwritten but that is probably irrevalent because it has the same date as the one installed by Installshield.
