After installing LabView 2014, all other OPC compliant software (Matlab with the OPC Toolbox, Wonderware SCADA, OPC Demo Client from Softing, ...) previously installed on my PC (Windows 7) started to have problems in browsing OPC Servers. They were unable to connect with opcenum service for listing installed OPC servers. After manually unregistering opcenum and registering again as a service (and cleaning the windows register), everything was solved.
So I guess there is a bug with the labview installer that mess things up with the opcenum service. I haven't found anything on the web but in case anyone has the same problem, this is the "manual" solution. Anyway, I would like to ask NI to revise the problem.
