I am getting this error "You must have a license to use this ActiveX control"

You must have a license to use this ActiveX control. (System.Windows.Forms)


Program Location:

at System.Windows.Forms.AxHost.CreateInstance() at System.Windows.Forms.AxHost.GetOcxCreate()

I converted a small project from VB6 to VB.NET, on one machine I can see my form but on another, I can't see the form in design time but the software runs fine.

    That was the common way that licensing was done back in the ActiveX days. Works just fine anywhere but putting it in design mode requires a properly installed license key. Seems you don't have one. You won't find one here, you need to run the vendor-provided installer and call them for support if that doesn't help. – Hans Passant Jul 28 '20 at 15:18
  • Thank you are you referring to Visual studio license or the Telnet Control license? – Dev Jul 29 '20 at 13:03
  • To the ActiveX license. See whether you have `.lic` file somewhere (could also be in `\Windows\System`). – Jimi Jul 29 '20 at 19:21
