WI Object Error: Object “tv” not found

Last updated: Wednesday, January 15, 2020

Applies to: ProVal and ProAdmin, version 3.13 and earlier 


When launching ProVal, you get the message “WI OBJECT ERROR: Object ‘tv’ not found”.



Register WinTechControls.dll (while having “administrator privileges”).

Example using Start>Run:

cmd /k “”C:\Windows\Microsoft.Net\Framework\v4.0.30319\regasm” “c:\proval\WinTech.Controls.dll” /codebase”

Example from Command Box:

“C:\Windows\Microsoft.Net\Framework\v4.0.30319\regasm” “c:\proval\WinTech.Controls.dll” /codebase

The above commands should be entered in one long line. The path C:\Windows\…\v4.0.30319 referenced above should be defined already as a result of having Windows .Net Framework 4.0 installed. c:\proval is the drive and path of the local ProVal directory.


WinTechControls.dll is not registered.
