Hi,
regsvr32.exe calls the dllselfregister function in a com dll
which usually will read from a reg resource in the dll and write the
registry keys needed with all the correct com information. Some people
have been known to modify this function to do other things along with
com registration.
When you use heat on a com dll it works out what the correct registry
keys to write are and places these into the installer.
You should use HEAT to gather this information.
See here for why...

Also you seem to be asking lots of questions that are easily found by
searching the the list archives here...

Subject: [WiX-users] Needs to understand how wix register the .dll or
.ocx?
Hi,
I want to understand how wix registers the components in registry.
When I run the heat .exe for files it generates code like.

</Component>
I want to understand how this code registers the component.
How it is different from using regsvr32.exe to register the component?
NeverOverwrite="yes" Permanent="yes" are these are the right attributes
if I don't want to remove/unregister the component.
Thanks,
