2147221164 - Class not registered

[Digit81]

Hello,

When I run the Labview block diagram below:

At the exit of the VI, arrow marked in red I have the following error:ILF_TG1##-2147221164 - Class not registered in GB_OPCDA_Open.vi->OPC_initSockets.vi->OPC RW Graybox.vi->OPC Read Main.vi"

I have installed labview Runtime, OPC Servers, NI Visa and other NI SW but I still get the same error, can anyone help me?

thanks

Hello,

I got the following solution from another forum post.

"Generally this means that the ActiveX Server has not been registered; typically due to the lack of an installer or such for the server that would perform this action for you. Have you had a look at registering manually? http://digital.ni.com/public.nsf/allkb/4F811A9B23F1D46E862566F700615B7A"
