x86 app read/write/backup on Win64 HKLM registry

Hi all,

I created a launcher for app which write settings to HKEY_CURRENT_USER\SOFTWARE\AppName\key
and HKEY_LOCAL_MACHINE\SOFTWARE\AppName\key

Unfortunately when running on Win64 the HKLM reg keys are not backup to portableapp settings and host system registry HKLM keys are not deleted.

On Win32, portableapp backup and deletion is fine. I read around seeing I need to use Custom code. Hopefully someone can help me?

Thanks in advance!
