Wix installer registry keys not getting created in

Question

I have a 64 bit machine in which I need to install a Windows service. This service was created using Apache procrun, therefore I need to create certain registry keys. These should go into the wow64 node as I expect them to, but they get created in HKLM/SOFTWARES instread of HKLM/SOFTWARE/Wow64 node. Below is my Product.wxs file.

I have specified the Win64=yes parameter. For the WIX setup project, I also specified "-arch x64" under project settings->Toolset->Additional Parameters. Still I get the registry keys created in normal HKLM/SOFTWARES and not in the wow64 node. Why is this happening? Please advice.

Answer 1

For keys that need to go to the 32 bit registry location (Wow6432Node) in a 64-bit installer you need to specify Win64="no"

It is a little confusing but Wow6432Node is actually the 32-bit portion of the registry on a 64-bit machine and NOT the 64-bit portion.
