About this task

Note: If the server appears in the list of Plant Applications Servers in the Plant Applications Administrator, double-click the server name to display the list of nodes.

Procedure

  2. If you are still unable to connect to the database, register the following controls using the command line:
    • Regsvr32 “C:\<Program Files location>\Common Files\Proficy\Plant Applications\PRMsgs.dll”
    • Regsvr32 “C:\<Program Files location>\Common Files\Proficy\Plant Applications\ProfCDG.ocx”
    • Regsvr32 “C:\<Program Files location>\Common Files\Proficy\Plant Applications\ProfSVR.dll”
    • Regsvr32 “C:\<Program Files location>\Common Files\Proficy\Plant Applications\PRUtils.dll”
    Note: The Program Files location varies depending on whether the operating system is 32- or 64-bit. For a 64-bit operating system, the path is Program Files (x86). For a 32-bit operating system, the path is Program Files.
