Some clarifiaction on registry cleaning

Thanks for any help.

Thank you for the wonderful product Ccleaner.

I'm trying to help an old gentleman with his Puter.

He had an old version of Ccleaner and an expired version of Registry Mechanic on his puter.

I updated Ccleaner to the latest with all the Registry goodies checked and uninstalled Registry Mechanic.

I then ran Ccleaner and it ran fine.

Question:

He is still getting a "Rundll" error. Does Ccleaner do the same type of job on the registry as say RegCure?

Should he have RegCure AND CCleaner with the Registry entries checked? If so what does the registry section

of Ccleaner do?

I'm kind of confused.

CCleaner doesn't "cure" the registry, it cleans the registry removing invalid entries. That error he's getting on startup I assume could be left over in the RUN areas of the registry, startup folder, or depending upon the version of Windows like say Win98 it could be from a system file, etc.

Thanks for replying.

He's running Windows XP home.

What can I do to solve his problem?

See if this helps.
