Error 0x80040154 class not registered

[Guest]

The application used to work fine, but today, in this code:

CType(Me.AxSSTab1, System.ComponentModel.ISupportInitialize).EndInit()

..Net shows the next error:

An unhandled exception of type 'System.Runtime.InteropServices.COMException'
occurred in system.windows.forms.dll
Additional information: Class not registered

Why is it?

Tnx

Hello Alejandra,

The application used to work fine, but today, in this code:

CType(Me.AxSSTab1, System.ComponentModel.ISupportInitialize).EndInit()

.Net shows the next error:

An unhandled exception of type
'System.Runtime.InteropServices.COMException'
occurred in system.windows.forms.dll
Additional information: Class not registered

Why is it?

The type of the variable 'Me.AxSSTab1' is, I assume, a control. From this
error, it appears that the control is either not registered or is not
responding as though it is registered.

Can you tell us the type of the control?
Can you look in the registry and make sure that this control is still
registered?
Are you sure that this control isn't failing on purpose, due to a licensing
issue?
