How to do if the following message appears during install:
This error occurs because an OPC server (or OPC client) is running on the machine at the time of installation.
ALERT tries to access OPCEnum.exe in read/write mode to retrieve version and update it if necessary.
Solution :
- Stop all OPC servers/clients before installing ALERT.
- Click on the "Ignore" button to continue the install. OPCEnum being already on the PC, it will work.
