I have existing VB6 program with CR-XI reports. Deployed and working. When adding a new report, I get error message (Invalid TLV record) when running on client PC. For ease of debugging, I can reproduct this error in a simple test. I created a report with text("Test") in page header. I created a new VB6 program with just a button and a crviewer. I call report when button pressed and the report works in viewer on client PC. I then add a parameter field to the report (which will prompt for user input). This works on the developer PC but I get the error message ("... Invalid TLV record ...") on the client PC. Does anybody know the cause and fix to this error?
