Remarks

32-bit application operating on a 64-bit system

On a 64-bit system, the 32-bit applications write into the registry from the following branch:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node

Handling the registry in Windows Vista

In Windows Vista (and later), if the UAC mechanism is enabled, you must have the administrator rights to write into "HKEY_LOCAL_MACHINE\SOFTWARE".

If the user does not have the necessary rights, the UAC mechanism performs a redirection to "HKEY_CURRENT_USER\Software\Classes\VirtualStore\MACHINE\SOFTWARE". The purpose of this redirection is to ensure the compatibility of the applications. The keys written in this directory can be read by the application that has written them.

Reminder: when creating the executable, a manifest can be included in the executable so that administrator rights are granted to the application.

Operating mode in GO mode and at run time

In GO mode (simulation on the development computer), RegistryValueType handles the registry of development computer.

At run time, RegistryValueType handles the Mobile Device registry (Pocket PC).

The differences between GO mode (simulator) and real use are presented in Differences between GO mode and real use.
