Error: sdeservice.exe unable to locate DLL

Error Message

Installing ArcSDE returns this error:

sdeservice.exe unable to locate DLL
The dynamic link library sde80.dll could not be found in the specified path...

Cause

ArcSDE for Coverages client not installed.

If only the ArcSDE for Coverages Server is installed on a machine that does not have ArcInfo, certain DLLs will not be installed. As a result, the error is returned during the installation. The installation may finish; however, the service will not be installed nor will ArcSDE for Coverages be available.

Solution or Workaround

  • Install both Server and Client on a machine that does not have ArcInfo installed. All the necessary DLLs will be installed and the service should start.
  • Install ArcSDE for Coverages Server on a machine that has ArcInfo installed. All necessary DLLs will be installed or will be used from the existing %ARCHOME%/bin directory for a successful installation to occur.

    Note: ArcSDE for Coverages is a stand alone application (Server and Client), this means it can be installed on a machine that does or does not have ArcInfo already installed.
