How do I use REGTLIB.EXE to unregister a type library

Question

How do I use REGTLIB.EXE to unregister a type library?

Is this even possible? When I type regtlib /? it displays no information at all.

Answer 1

Short answer:

regtlib -u [filename]

Background:

There are (at least) two versions of regtlib.exe. Since at least version 6.0.81.91 (having file size is 40960) it DOES support -u to unregister a .TLB file.

The version that does not support -u has no version information, which means that when you view its properties in Windows explorer, there is no version tab. And the file length is 30720 bytes.
