Here are some more details regarding registry paths.
Since 64bit Windows re-routes all registry keys for 32bit programs automatically (HKEY_LOCAL_MACHINE\SOFTWARE\ to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node), Adiscon decided in the course of development that the 32bit as well as 64bit registry keys of the service should use the „HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node“ subkey.
But for your case, this is rather problematic since you need a registry file for 32bit and for 64bit systems. Thus we decided to use a workaround, namely to use the parameters key in the service area. In the services subkey of the registry is no automatic mapping for Win32/64 applications and thus you can use the same registry file for all systems.
