What are "Type Libraries" ? Should I fix them ?

CCleaner for Windows

Hello,

In the Registry section, there are many items to choose.

One of them is "Type Libraries."

When I run "Scan for Issues", more then one hundred "Missing TypeLib Reference" appeared.

What are they? Is it save to fix them?

Thanks.

Well I fix those invalid type libraries and that has not caused me any problems. But make a system restore point first.
