This would also work without to much work:

			local name, title, notes, loadable, reason, security, newversion = GetAddOnInfo(i)
			if name ==  "NameofAddon" and loadable then
				enabled = true
				break
			end
		end

You can use either one of these of:

name - Name of the addon (name of the addon's folder and TOC file) (string)
title - Title of the addon (from the Title header in the addon's TOC file) (string)

I personally would use name because some people use different titles from the addon folder in their .toc files.
