About some features of writing distribution packages on NSIS for x64 systems
I came across unexpected (for me) NSIS installer behavior for 64 bit systems.
It is about accessing the Windows registry. For a long time I could not understand why I can get some values from the registry with the standard NSIS tools, and some others I can not.
Answer: in 64-bit systems, the keys are in several different sections - 32 and 64 bits. From the reged for the user, these features are not visible - they are transparent. And, accordingly, to access these keys from NSIS, use the modifiers "SetRegView 64" or "SetRegView 32".
Example:

P.S. I wrote it because I spent quite a lot of time searching for a solution to this problem. Use!
P.P.S. $ {DbgMessageBox} is an internal function for displaying values during debugging.
