Details

Note: You can access the latest version of the wwClient 8.0 on the AVEVA site from the following link. If downloading from a Windows 10 or Server 2016 and above please remember to Unblock the download before accessing the zip in anyway.

Right click on the download, select properties.

Check Unblock and apply.

Once extracted be sure to place the utility in the same directory as wwsl.dll as a best practice to ensure the utilities accuracy.

C:\Program Files (x86)\Common Files\ArchestrA

It is NOT a good idea to copy wwsl.dll to different parts of the system (even though you may find material suggesting otherwise). wwClient will run fine without finding the suitelink.dll and it may work most of the time but there is the possibility that it will may inaccurate values. 

As you use the utility you may find the items list drop down becomes cluttered with wrong entries and "old" addresses.

To resolve, launch the registry editor.

Locate the following Key:

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Wonderware\wwclient\Item]

Clear out any unwanted Items under the Item key.

You may also want to clear the LastItem Key.

When you launch wwClient again the Item list dropdown should now be empty.
