Copy all registry entries from one location to the other in Inno Setup

Question

I am using Inno Setup to copy all entries in the registry from one location to another. Can you please advise on how to do this? Thanks.

There's no easy way to copy registry tree elsewhere.

• You can use WinAPI RegCopyTree (but you will also need to import and use RegOpenKey, RegCreateKey and RegCloseKey).

• If you want to stick with plain Pascal Script, you would have to use RegGetSubkeyNames and RegGetValueNames to collect all subkeys and values and copy/write them one-by-one.

  For some example, see Copy32BitUninstallKeyTo64bit in Inno Setup: Keep existing 32-bit installation path for upgrades, use 64-bit path for new installations – though it does copy only all values (and of specific types only), not subkeys
