The Windows 64-Bit Registry on x64 versions has a new section "Wow6432Node" in each major Registry hive.
in the proper position, many older 32 - bit registry .REG files will suddenly become functional. This applies to things like license keys,
settings entries, and some shell extensions.
Look at where your .REG script put the original entries, and see if there is a corresponding Wow6432Node to match. Modify your
script to put the entries under that node.
