Wonderware Information Server - Table Weaver Manager HTTP 501 Error

Issue
 
When using Table Weaver Manager in Wonderware Information Server (4.0), a HTTP 501 error occurs when clicking on the following links under the Table Weaver Manager node:
  • Content Units
  • Queries
  • Links
  • Displays
  • KPIs

Cause

This is due to a missing or unregistered dll, wwCntDef.dll.

Fix

Check the following file exists within the Information Server installation drive:

<installation drive>:\Program Files (x86)\Wonderware\SuiteVoyager\MTSComponents\wwCntDef.dll

If the above file does not exist then copy it from the Information Server 4.0 installation disc (d:\\MTSComponents\wwCutDef.dll).

register the dll. e.g. regsvr32 "C:\Program Files (x86)\Wonderware\SuiteVoyager\MTSComponents\wwCntDef.dll"
