how to unregister typelib(*.tlb)?

[wuhao]

I have sought for the help file, only to find System.RegisterTypelib, how can I UnRegister it? Thanks.

You could locate the regtlibv12.exe utility and call it with the "-u" parameter to uninstall the typelib from the system.

File.Run(sPathToRegTlib, SessionVar.Expand("-u \"%AppFolder%\\thefile.tlb\""), "", SW_HIDE, true);

Thanks, that worked! But why does the setup factory provide the unregister function only for activex and font? Are there any problems for typelib?

I am not sure why such an action wasn't made available. I have submitted a suggestion for this, perhaps it can be added in a future release.
