Windows 64 bit
When a 32-bit Windows application is executed on Windows 64-bits, it runs under the wow64 subsystem (WoW stands for 'Windows on Windows'). This has the side-effect that access to certain parts of the registry and filesystem gets transparently redirected. This is irrelevant for most applications, but because InstallBuilder itself is a 32bit application, if you are using it to install a 64-bit application you need to tell InstallBuilder to disable these redirections. You can do so with this settings:
The above is equivalent to individually disable filesystem redirection with
<wow64FsRedirection action="disable" />
and accessing the 64bit registry using built-in actions such as <registryGet> with the option wowMode="64"
Please note that for installing 32-bit applications on Windows 64-bit, in most cases these changes are not necessary.
