and what if need to create search for registry, where will i need to point to?

And what will happen with all this configuration if i only change package to be 64bit?

will search work or i will ned to set Search the 64-bit portion of the registry??

Hello,

That is called a registry redirection (it can happen to files, too, hence the "Program Files (x86)" folder).

Basically, a 32-bit process on a 64-bit machine will redirect its resources in the 64-bit portion of the OS so the OS knows to better manage them.

These resources can be either registry entries, files, etc.

In your case, if you create a search, it will automatically look under WOW6432Node unless you check the "Search the 64-bit portion of the registry" option.

Thanks for the fast reply, but what will happened with all configuration only if i change installer to 64 bit package, then will be search in WOW6432Node or not? should i enable Search the 64 bit portion of the registry or not? because now i will run 64 bit package?

Hello,

If you change your package type to 64-bit, then the searches will no longer be redirected under WOW6432Node, so no, enabling that option is not needed anymore.
