Hi all, Having a problem with reading the registry of a Vista 64-bit machine with a LabVIEW 8.X 32-bit EXE. I've read a little about the issues. Can someone tell me is there a work around with LabVIEW 8.X? I understand that Vista 64 divides the registry into a 32-bit and a 64-bit version. Is it not possible to access (read/write) the 32-bit version of the registry using a 32-bit app? Cheers, Battler.

I duplicated the whole hierarchy, but in this ZIp file is AIT - WinAPI - Open Registry Key (WOW64 Support).vi (in the WinAPI\Registry folder). It is almost a drop in replacement for the standard NI Open Registry Key VI (8.6). It has one new option - Registry to Access. You can select Native, 32-bit, or 64-bit. Native is whatever bit level your app is running. So, LabVIEW 32-bit would access the 32-bit registry on a 64-bit OS. 32-bit and 64-bit access those specific registries. If you try to run on a 32-bit OS, the VI will force you into Native mode. The VI checks for WOW64 support or 64-bit OS (note that a 32-bit application will not indicate it is running on a 64-bit OS, which is why we need to check for WOW64 support). Based on the registry to access and the OS, the code ORs the proper bits for the security access. More info can be found via Google and MSDN.
