I am using multiple controls from a third party provider that apparently utilize classes in the mscomctl.ocx file (treelist and listview controls). I have multiple computers that have used these controls successfully, however, one machine (a Windows XP machine) did not have this file. I got the error '...not properly registered on this computer.' when trying to instatiate these objects. I copied the mscomctl.ocx file to the windows\system32 folder and used regsvr32 to register the control.

Now I am getting the 'Class is not licensed for use' error. How can I resolve this issue? I use InstallShield Express to create setup files for this application. Do I just need to add a control library from there, and if so, which one? Any help is appreciated.

TIA
