Hi,

I am using PB 2019 32 bit application on Windows 10 64 bit.

when I call RegistryGet function as in this example:

RegistryGet("HKEY_LOCAL_MACHINE\Software\Intercad\Polis\comune","comune",RegString!,gCodiceComune)

i got the registry value

from HKEY_CURRENT_USER\Software\Classes\VirtualStore\MACHINE\SOFTWARE\WOW6432Node

and not from HKEY_LOCAL MACHINE.

the same with RegistrSet function.

Can You please tell me the reason and if there is a way to make it work correctly? 

 

Thanks in advance

Greetings, Mario -

You are likely the benefactor of Registry Redirection, courtesy of Microsoft:

https://docs.microsoft.com/en-us/windows/win32/sysinfo/32-bit-and-64-bit-application-data-in-the-registry

If you absolutely have to read values out of the HKLM hive with a 32-bit app, from what I read you'll need to disable/enable registry redirection using the RegDisableReflectionKey and RegEnableReflectionKey Windows API functions, since there are no PowerScript functions to accomplish this, as far as I know.

Perhaps a separate question posted to the Appeon Community asking anyone if they have disabled/enabled registry redirection would provide you with some tips or code samples.

Good luck!
