I've been searching on the net for information. I found something on a forum from someone who couldn't merge, although his story is a bit different than mine. Frankly, the discussion went over my head, so I don't know if it is relevant. This is the solution they found:
"Hi, looks to me like you have .reg associated with script sentry, as you have this disabled then windows cannot find the association. Go back to Welshjim's post and his attachment select edit and change open to regedit.exe"%1" , set as default. You can easily test your .reg associations by opening regedit and selecting any sub key and exporting to desktop save as .reg and double click to merge into registry."
