Oh, dear sweet and fluffy Zebu! You have done gone and re-opened a can of worms. And you have been here about 2 years, haven't you?
OCDO is a site pretty much dedicated to te open carry of handguns. We occassionally discuss concealed carry and the process whereby CHPs are issued, but usually only as it relates to the extra-legal or illegal activities of the Clerks.
The answer to your question is: "It depends." Some say if you ever had a CHP but let it expire it's still a renewal. Others say it's a new applicatiopn. Why do you care, if you are bound and determined to get a CHP?
Just go through the steps and let the Clerk pick which box to check.
Read up on what is permitted to be asked for, and know what is BS that you need to tell the Clerk is not allowed to be done/requested, and go in on the 46th day after the date stamped on your receipt and demand your Temporary CHP if the real one has not yet arrived.
And pray that Peter Nap considers this sufficient and does not add his thoughts - you really don't want to read them.
