SendRegistry does not work with registry virtualization. I need to send HKEY_LOCAL_MACHINE\Software\Test from 32-bit application under 64-bit OS and this key is not found, because CodeSite looks for HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Test. There should be another parameter in SendRegistry, Flags or KeyAccess, where KEY_WOW64_64KEY flag to disable registry virtualization could be entered.
