If it's not there, try looking under C:\Program Files (x86)\OPC Labs\QuickOPC x.yy\Bin.

If it's not there either, you might have installed QuickOPC for .NET development instead of COM development (the choice is on the second page of the Setup program) - in such case, simply reinstall, choosing the right option.

For some reason EasyOPC Options Utility is not visible in the Start menu. I can't find it on the Apps screen of Windows 8.1 either.

Can you please run the EasyOPC Options Utility (available from the Start menu), and under the "System Parameters" tab, check the settings in the "COM Registration" group? (see picture).





If they do not look like on the picture, please set them as such, i.e.
- "In-process server" unchecked, and
- "Local server" checked

and retest.

Thank you

Can't Creat object in Windows 8.1 64 Bit was created by Dirk
When i try the following sample in Vbscript i get a Can't create object error. I suppose this could be a call to 32 bit com object in a 64 bit environment but i'm not sure yet.

The customer has a an application that allows running scripts and it would be handy if he could write a value from this application directly.

Can this be done ?

Rem This example shows how to read values of a single item, and display it.
Dim EasyDAClient
Set EasyDAClient = CreateObject("OPCLabs.EasyDAClient.5.2")

Dim value: value = EasyDAClient.WriteItemValue("", "OPC.SimaticNet.1", "S7:[S7_Connection_1]QB0",1)
[Q0.0] = value
