A user may encounter OPC installation errors when installing the PerceptiveAPC suite of software to a machine on which an OPC server is already registered. To rectify this, the user should deregister the OPC server that is in the executables folder, and register it
To deregister an OPC server
Launch 'cmd' (command line) as an administrator (this can be found by right-clicking on the 'cmd' tool). Navigate to the APC software executables folder - this is typically located in:
- C:\Program Files\PerceptiveAPC\VX.X\<SoftwareType>\Executables
where VX.x is the software version (e.g. V7.2), and <SoftwareType> is the APC software (e.g. PharmaMV, NutriMV, WaterMV or PerceptiveAPC).
To deregister the server, then type:
OPCServer_DA.exe /UnRegServer
The name "OPCServer_DA.exe" is the name of the OPC server from version 6.0 of the software. In the software versions prior to this, the OPC server name was "opcserver.exe".
To re-register an OPC server
As above, launch 'cmd' (command line) as an administrator (this can be found by right-clicking on the 'cmd' tool). Navigate to the APC software executables folder - this is typically located in:
- C:\Program Files\PerceptiveAPC\VX.X\<SoftwareType>\Executables
where VX.x is the software version (e.g. V7.2), and <SoftwareType> is the APC software (e.g. PharmaMV, NutriMV, WaterMV or PerceptiveAPC).
To register the server, then type:
OPCServer_DA.exe /RegServer
The name "OPCServer_DA.exe" is the name of the OPC server from version 6.0 of the software. In the software versions prior to this, the OPC server name was "opcserver.exe".
