Check if OS is 32 bit or 64 bit before application install in C# windows application

Question

I want to validate a 32 bit application install on a 64 bit machine where I need to show some information to the user before installing the application. Is this possible?

I am using the launch condition (Not VersionNT64) for 32 bit and (VersionNT64) for 64 bit but that is not working properly!

Answer 1

I'm not quite sure I understand your issue, but if I assume that you have two different installers, one for 32bits and one for 64 bits, you would have to make a small executable that will wrap the two installers and select the correct MSI file.

Environment.Is64BitOperatingSystem

will show you what kind of OS you are currently on.
