the problem is caused by Ignition could not find the right COM object to create. so, install OPC Core component and then reboot the machine, should resolve the problem.
My machine is 64 bit windows, choose x64. during the intallatin process, it might come up with a question, telling you that some process need to stop before proceeding, like OpcEnum, I just kill that process and click cont. (beware, do this at your own risk)
I’m trying to connect to an OPC DA Server.
I installed the OPC Core components (several times) with the same architecture than my OS. I also rebooted (several times) but I keep having this error when trying to connect to my OPCDA Server :
com.jniwrapper.win32.com.ComException: COM object method returns error code: 0x80040154; REGDB_E_CLASSNOTREG (Classe non enregistrée)
From what I understand, this is caused when Ignition can’t access to the OPC Core Components. I can’t figure why.
I can define the connection to my OPC Server (it appears in the list)
The OPC Server is local
Another OPC Client is working well
COM / DCOM settings set to full access to Everyone and Anonymous logon
Ignition 7.9.3 / Java 64 bits / OPC Core Components 64 bits installed (it apprears in the Windows Programs list)
Rebooted several times.
Followed and applied the troubleshooting guide provided in the previous posts
How can I make Ignition use those OPC Core components (it seems that the problem is really here).
