Install fail on Win7 pro 32 bit

Hello there,

Installer does not work on my admin account in Windows 7 pro 32 bit ... all Win stuff up to date, Malwarebytes and Bitdefender full scans in the clear, Intel drivers updated via their desktop app.

Other Windows failures including at #3609 but not this early:

"The installation package is not supported by this processor type. Contact your product provider."

I realise win7 is on the way out, and only a 32bit version but be great if I could still get use out of this old desktop.

By comparison installing KB on my Linux laptop was a breeze via curl, which makes for a nice reversal, for a change, so I've got that going for me.

Start by reproducing the installer failure on Windows 7 Professional 32-bit using the reported Intel Core i5-3470S system details and the error shown in the issue. Investigate the Windows installer entry point and its processor or architecture checks. Done means the Keybase installer works on the reported platform or the unsupported-platform behavior is clearly documented.
