GitHubDesktop.exe "not valid Win32 image"

Apparently today at 15:48 EDT, GitHubDesktop.exe was updated to v2.5.4 on my Windows 7 64 bit laptop.
The image cannot be started “not valid Win32 image”.
Was able to run the v2.5.3 GetHubDesktop.exe w/o problems.
Bad update?

Hi @hellersuperuser :wave:

Could you list the steps to get to this point?
Have you installed the latest version of Desktop?
