Hi friends
users getting following error when using an activex control (TX control)

"Error message is OLE error code 0x80040112: Class is not licensed for use"

i can register fine and no errors but as soon we open screen that has this control they get above error.

its working fine until they installed new server(OS:Win 2003).
yes i checked all obvious things like user permissions,OCX versions etc., but they all fine.

any ideas on how to trouble shoot this one ?
Thanks for ur help
