This is normal. From the message you have posted, I've understood that the application is on 64bit mode but you have 32bit mode. You can run 32bit applications on 64bit versions of Windows but not vice versa. Of course, there are exceptions but they're limited and require installation of additional files to enable 64bit support for certain apps only. However, my recommendation is to access the website you've downloaded the package from and choose the 64bit version instead. This will enable compatibility with your operating system.
